I have a 8lb and a 36 lb dog. Does anyone have the medium one to tell me if my 8lb dog would be able to push through the flaps? Thanks

We have the large with a 75lb and a 50lb dog. There will be no problem with an 8 pounder using the medium flap. This is old dogs, new tricks, using the double flap. They hesitate to use the double flap for a while. We started with a single flap and added the second flap later.

I have a 5 lbs. cat, Sassie, and a 14 lbs. cat, Cheddar. Cheddar is a little fat and just makes it through the medium door OK. Sassie has to work a little to get it open. I put a stick though the opening for a couple of days to help them get the idea. Good luck.

The dog would have to be taught, but if it was not too high for it and it had the will go go through it, the dog would be able to go through the door. Good luck.

We have a medium one that is successfully used by a 45(!) lb well-fed dog (yes, we can read, but the door was here before the dog). We also have cats ranging from 6 to 16 lbs who all get through it just fine, so an 8 lb dog probably would once she got the idea. (And the very best training aid is watching the OTHER critters going in and out!) The flaps are heavy, but the smaller cats have learned to push aside a corner and squeeze on through.

I have two 15 pound dogs and 4 cats. None of my cats are very big. They all go through nicely. The 36 pound dog would NOT fit through.

I have a 3.4lb yorkshire terrier and she hasn't been able to squeeze through. She's not overly adventurous though. If your little guy is pretty adventurous, then I would be worried about him trying to squish through, but in general I think it is fine for our tiny little ones.

I have a small dog, 12 lbs. and about 3 years old. He has no problem. I also have an older cat - 13 years old and he has no problems with the flap either. This is a great product. Installation was a little bit of a challenge. I called it quality time with my husband. PS - We are still married.

My dogs go back inside very easily. It took them a couple of tries and first, but now they run in and out all the time. I don't think a 25 pound dog would have problems, but all of my dogs are 60+ pounds so I can't say for sure. I can say this is a really strong, sturdy dog door!

I will chime in and also add that I believe that this will work for your dog. We have 2 bischon-poodles mix pups that are about the 18-22 pound range. This door is perfect in every way. My bro-in-law has a 80-90 lb black lab that squeezed himself through the door a couple of times because he saw the smaller dogs do it. Anything bigger than 50-60 lbs would be too big for this door IMO. Anything less is great

I've got a Medium size for my 3 dogs which are all around 27". I'm able to adjust it to fit all 3 of their body types which include: a wide deep chest, a narrow deep chest, & a wide shallow chest. Since u have a pup that is still growing & a mature dog, I would buy one for the mature dog but NOT for the pup since you don't know what it will mature to. Also, the backpack doubles the impact of the walk (like when we have a backpack on) so I wouldn't have the pup carry a pack since it's body is still developing.

We have a schnoodle, about 18 lbs, and a smaller maltipoo, and the door is big enough for them to practicality go through side by side. In fact, we have a toddler (24 lbs) and he has used the doggie door with no issues. The flap measurement is accurate. I would suggest cutting a hole in a cardboard box the correct size, and testing it with your dog. I do suggest that you be ready to purchase additional weatherstripping, as what's included is inadequate.

My dog weighs about 50 lbs and she has plenty of room. A larger dog should have no problem. I'm an 5'2" average size person and I could likely fit thru :)

We were really concerned that our dog wouldn't figure out how to use any flaps, let alone two (she's quite timid - afraid of even nosing open an ajar door). We taped up both flaps for a week until she got used to going through the opening. Then we dropped one flap and spent a couple of days opening it for her before she figured out she could do it on her own. We were really concerned that dropping the two flaps would be a deal breaker but much to our surprise, one fell down in the night and she barely noticed. So, in short: I don't think it will be a problem especially if your dogs already use a dog door with a flap.

Bought this for my 11 lb. JRT. I must have bought the smallest one, but don't really recall because it was almost a year ago. The tension was way too tight for her, she couldn't pull it out at all. It was actually comical - she just stood there and looked at me like "what the heck"! I had to return it. Probably be ok for a 35 lb dog though. Good luck!

My largest dog weighs about 11 pounds and he takes up about 1/2 of the space of the medium. He has plenty of space to sprawl out. So it may work for you. These seats were larger than expected for a medium. I have two of these in the back seat of my Honda CRV and there is less than a foot between the two.

I have a 55 pound retriever mix and almost two of her could fit on the medium which is what I bought. I am sure if they have larger sizes the mastiff would fit nicely. She has hip problems and it is her go-to space now. She loves it and so far it has not lost its shape.

I do not have an answer to that question, but I have 3 dogs who use the door very frequently and have not had an issue with the flaps in the time I had it which is close to 2 years now.

I think it will be to small .I have a 4 lb dog and she fits well with room to spare but I wouldn't go over a 8 or 9 lb dog . I hope I could help .

We have Shih-tzu's that weigh about 16 pounds. They have separate crates but can both sleep together. A medium size dog could probably fit with b=no problem.

My dog is a lab size. About 80 lbs. And he has no trouble. It is a rather large opening and i have a concern that a small person could climb through the opening but then they would meet a rather big angry dog on the other side.

I have a 8lb Morkie and she fits nice in this kennel. You could have a larger dog but I wouldn't go any larger than 15-20lbs. I like to make sure they have enough room to move around. Hope that helps a bit
