Description
The Doggie Dooley Model 3800X is an in-ground dog waste disposal system designed to help manage pet waste conveniently in residential yards. Installed below the surface, this septic-style unit helps break down dog waste naturally in the soil, offering a dedicated outdoor disposal solution that keeps cleanup centralized and out of household trash. The system measures approximately 16 x 16 x 8.5 inches and is suitable for homes with up to two large dogs or four small dogs, depending on usage and soil conditions. Installation is simple: dig a hole in the yard using a post hole digger or garden shovel, approximately 48 inches (120 cm) deep and about 8 inches in diameter, place the unit into the ground, and position it so the lid sits at ground level. Once installed, add water and dog waste as needed. For initial setup, add approximately 5 gallons (19 liters) of water to start the breakdown process. Add approximately 1 gallon (4 liters) of water each time waste is added to help support proper flow and breakdown inside the unit. For maintenance, add water regularly and use Doggie Dooley Waste Terminator tablets weekly to help support the natural breakdown process inside the unit. As the waste decomposes, liquid by-products disperse safely into the surrounding soil. The system works with natural soil bacteria to continuously process pet waste below ground. For best performance, the system should be installed in well- drained soil and climates where ground temperatures remain above 40°F. Doggie Dooley provides a practical backyard solution for pet owners who want a dedicated underground disposal system that helps keep lawns cleaner and reduces reliance on trash bags for pet waste. This product includes extended product support for up to 12 months from the date of purchase for defects under normal use. For assistance, please contact the manufacturer.

We have two large dogs, so the idea of not having to carry out heavy bags of poop was very appealing. After using this for about six weeks, I can honestly say it’s been a great solution for us. It works well and has made cleanup much easier overall. The opening could be a little bigger when adding waste, but it hasn’t been a major issue for us. Be prepared to dig a pretty deep hole for installation. Also, with two large dogs, ours is starting to fill up, and the tablets included don’t seem to break everything down fast enough. I’ll likely look into other options to help speed up the process. It is very lightweight and the lid is durable. It helps with odor a lot! It makes clean up so easy i pick up two times a day now! One thing I do like is that it’s not a permanent setup. You can move it if needed, which is helpful. I also wish the lid came in more color options, but that’s a small detail. Overall, we’re very happy with the purchase and it’s been a big improvement for managing dog waste.

This is one of the most exciting products I've heard about. I have been wanting to get rid of my garbage service for a while now, compost most everything and have very little waste. Well, dog poo was a large portion of our garbage, as we have two labs. Throwing it at the back of the yard to decompose naturally was not an option. My wife told me about a septic system specifically made for dog poo that she had heard about. I was like "Seriously?! Awesome!!" So, a quick search on Amazon brought me to this item. I had no hesitation in ordering this item based on reviews and the whole concept. I'ts been up and running for about two weeks. I use two tablets per week and seems to be working just fine. Not sure if the powder is any better. At this point I would say buy it! Notes: They say to dig a four foot hole, and that's it. They don't say to fill it with anything. I can't imagine the plastic cover being able to support over forty pounds. I decided to fill the hole with drain rock until this item sits on top of the rock and is flush with the ground. How it works: You buy it, bury it, fill it with water, throw a couple tablets in to get the bacteria started. Then throw a day or two worth of poo in, but no more, you don't want to overload the system. Each day you pour a gallon of WARM water in to "flush" the system. This stirs everything up, raises the water level, and empties waste into the four foot hole you dug. Then scoop daily poo into this unit. Is this smelly? Yes and no. When it's closed for the day you don't smell it, but when you open it to make a deposit, yes it's very smelly! Overall this won't stink up the whole neighborhood. Might not be best put in a place of direct sunlight for most the day as the sun will break down the plastic very fast. I believe the fact that the bacteria doesn't work well below 40 degrees, I don't work well under 40!! Highly recommended!!

I wanted one of these, but decided to use an old garbage can instead. I dug a deep hole, cut the bottom off the can, only to discover that I did not have a lid for the can. I REALLY like the lid on this product, it looks durable and easy to use. I did not relish the though of lifting the lid every time I scooped. So I bought one of these to use in my hole about a month ago. Well, it turns out this is a mini septic tank. The bottom can is sealed on the bottom and has an overflow tube. It uses the type of composting that is in water. You add enzymes to break down the waste, and then what's left flows over the top of the overflow tube and into the ground. I also discovered, after reading the instructions, that this will not work in clay soil. My soil is so clay, I added a little water to make it easier to dig, and the water stayed for days! Seeing that this type of composting would not work for me, I modified mine. I cut the bottom off, used the can as a lid, (I know an expensive lid!), and used it that way. My hole, big enough for a garbage can was too big, so I cut pieces of my garbage can (plastic) and put it around the Dooley and filled in my hole around it. It works great so far. The top flange and the lid itself are plastic, so I worry about sun damage and cracking, but so far so good. Since my soil is clay, water drains very slowly out of my hole. I dropped some of the enzyme pellets in anyway to see what happens. There is still a lot of water in my hole, but so far no smell. It has been cold, so it might be worse in the summer. LOTS OF FLYS!!!! But I figure better inside the Dooley, than outside in the yard. At least the spiders will be able to feed of the Dooley that having to build webs all over the yard like they do now. So check your soil to make sure it can absorb the water from this mini septic tank before buying.

I had an older model dog dooley in the form of a large plastic pyramid open at the bottom that you buried in a large hole in the ground. This served me well for over 20 years, but the plastic lid at the top eventually broke from usage and fatigue, though the underground structure is still working to this day. This new model is made of steel, and is closed at the bottom. It is installed by digging a deep and narrow 48"x14" hole in the ground. I made the hole too wide, and had to use small rebar bars at the top to make it fill, and then filled the too-wide mouth of the hole with gravel. I could have dug another hole, but the initial hole was hard to dig because of roots, so decided to improvise. Make sure that the hole is narrow. Once the digester is installed, it is very easy to operate. You need to add water periodically, which overflows from the inside into the deeper hole. The opening of the digester of the digester is wide enough that the matter inside can be easily turned periodically. This helps breakdown clumps in the matter, spread the enzymes, and add oxygen. Eventually, I presume that the hole in which the digester is installed may become full, and may have to be emptied or a new hole dug, but that will probably take years. Overally if you are interested in an ecological way to digest your pet waste that does not involve plastic bags and throwing poop in your trash, I highly recommend this system. It is well designed, well built and very practical. It does take a little work to install, and light periodic maintenance.

Pros: I guess it works. I dug my hole, installed and backfilled. After routinely placing dog doo in the disposal for about a week, I noticed it was staring to fill up. But then, a miracle happened, it leveled off. It's currently about 2/3's full and that's about where it stays. So, my guess is the little poo eating microbes needed a little while to get going and are now doing my dirty work. I don't keep it filled with water all the time, that's a ridiculous expectation. But I do try to give it a good soaking about once a week. That seems to be working. Cons: As others have mentioned, the hole required is quite deep. Four feet below the bottom of the 16" deep Dooley. I bought the cheapest post-hole digger HD had and went to task. Luckily, where I live the soil is relatively soft. But If I were back in AZ, it would have been a nightmare. The build quality is quite terrible. It's extremely thin plastic. I had little faith in it's ability to retain soil on its own, so when I backfilled, I mixed in a little portland cement with the dirt to help shore things up. I also think it's pretty shady the company posts a diagram that's intentionally mis-scaled. In the product pics, both the 48 and 16" holes appear the same depth. ***My Rating Criteria*** Build Quality(47.5%) - 3.0 Stars Efficacy(47.5%) - 3.0 Stars Post-Sale Support(0.0%) - n/a Packaging/Presentation(5.0%) - 5.0 Stars WEIGHTED AVERAGE(100.0%) - 3.1 STARS

I installed this myself which is saying something considering I’m a 50 year old woman. The digging was made much easier after I used a 36” auger drill attachment to loosen the soil. I dug the hole with a post hole digger, put some drainage rocks in the bottom of the hole and set the dooly flush with the ground. Only problem I had was due to the soil where I live, it’s mostly sand and the hole kept caving in so I sunk a 8 inch drain pipe with holes drilled through sides down into the hole to shore up the walls. Next I added the water and the tablets that came with the product and it’s been working ever since! I haven’t had any problems with odor and each time I add a fresh pile of dog poop the previous one isn’t there. The product seems sturdy enough to do its job. I’m debating on moving it to a new location closer to my garden hose because it needs water to work properly and I believe it will hold up well if I do move it Pretty cool product. I keep my garbage can in my garage and it doesn’t smell like dog crap since I started using this. I have one large golden retriever but she has friends over often who like to poop here so I use the product a lot. Hope this helps anyone who is on the fence deciding if they want to buy this, I’m glad I did!

It was months before I figured out a way to dig a hole deep enough. We attempted to dig it with a shovel and post digger. We also had a landscaper attempt to dig the hole in three different spots with an awl with no success. He gave up. Installing this requires digging a 64" deep hole... which you don't really understand how deep that is until you try to do it. This is much deeper than ANY post hole you'd need to dig and soil gets rockier and harder to dig the deeper you dig (at least, that's been my experience). The larger width hole isn't bad, but then you're stuck trying to dig a very thin hole for 48". Again... this is really quite deep. And unlike the larger area, you can't get leverage to lift the rocks up. You don't want to dig the thin hole wider to get rocks out because then it won't support the Dooley as well. If you want this product, I highly recommend digging the hole FIRST, then ordering it IF you're able to dig a hole to the specifications. It's an expensive item to purchase and not particularly useful if you can't bury it in your yard. Also, you want to make sure your soil has decent drainage wherever you put the hole. Otherwise it's a bad spot for the product. I finally managed to dig this using a dig bar (picked one up at the hardware store) and a post digger. A dig bar is essentially a straight pointed metal rod and it's heavy. Some are lighter than others so I recommend finding the lightest option if you are concerned about your ability to use it. I'm pretty sure they're about 16-17 lbs. When you use the dig bar, you can thrust it down to break up soil and rocks, allowing you to use the post digger to then scoop up the dirt and rocks. This allows you to dig straight down so your shelf can properly support the Dooley. You need the smaller hole to be as straight down as possible and the shelf to be as perfect as possible or you'll have dirt and rocks slip back into the hole when you place the Dooley back in the ground and fill in around the sides of it. In terms of the actual product it's a cheap, thin plastic. It technically keeps the scent in (although I'm not sure how well because we haven't had it installed during the hottest part of summer yet), but the plastic is so thin that I am very concerned about the ability of it to support any weight. Seeing a portion of it is buried under the ground, I surrounded the area with rocks to mark off where it is. But I have two young kids and I am still concerned that if one of them stepped on it, it would break and collapse. If I push on the soil above the Dooley, I can see everything flex. I'm also concerned about if it will stand-up to the weight of heavy snow. I don't think it would collapse under my dogs weight but I haven't seen either dog try to walk over it (and the heaviest is 50 lbs). I also don't see the lid lasting long if my dog decided he was interested in chewing it. In the winter (assuming you live in a cold area), the poop won't break down so you can't use it for those months. I didn't see it breaking down particularly well in the Fall, but I really can't attest to that as I installed this later in season. The ground wasn't frozen (obviously) but cool weather doesn't really do much for speedy composting. My thought is that eventually, even if the poop breaks down and composts, the hole will fill up and you'll need to relocate the Dooley. Now... Once you've dug this hole once, you're probably not going to be keen on this, particularly as I can only imagine what a smelly venture this is. Overall, I just don't think this product is practical for most people. I wanted this to work so bad. But you could probably just dig your own holes, use the enzymes separately, and save yourself some time and money. I also think it is potentially unsafe if you have children that could be in the yard (any deep holes at all). There's another product available that hooks up direct to your septic. I haven't tried it, but it looks like it might be a better long term option. Not sure about child safety on it. Don't think it's for sale on Amazon (or it wasn't when I bought this) and it's probably more expensive than this by a lot.

WOW, this dog poop septic tank... What an invention. My husband got this installed fairly quickly, thanks to my digging Husky, she had a pretty big deep hole dug in our yard, so she did half the work for my husband, we figured why not put it where Ellie wants it ;-) At first he didn't really follow the directions and didn't dig it out properly, the digging measurements were a bit confusing to him apparently because when our daughter and so-in-law stopped over, my husband was showing them, but my son-in-law looked at the directions while talking to my husband and he didn't have it far enough in for the "French drain" or something like that (son-in-law is a plumber, so by nature he was curious) So the next morning my husband took it out and dug to the dimension my son-in-law told him... Worked like a charm. Yes, it is disgusting in there once you start putting the poop in, but using the tablets and flushing it often does help. The smell stays contained with lid closed. I like that I can just pick up the poop, step on it to open, drop the poop and let it close. I learned the hard way to make sure you are standing behind it and don't drop it from too high, the poop water will splatter up on you. When you add a gallon or more of water, it brings the water level up and then down the pipe into the ground. It as if you are watching it flush, although the brown water is still there, that's all it is, no chunks of poop at all. Having 3 dogs, this is very useful for us!
