Doubt it. I'd go with the large, measure the chest size and around the neck.

Medium. My Beagle mix is 45 lbs, and the medium fits her well, but would fit a 55 lb dog better, in my opinion.

I am not sure if this will help but my dog is about 40lbs and an Italian grey hound mix. She is wearing a medium with the straps adjusted as tight as they can be. I think bull dogs tend to have wider more barreled chests, so maybe a medium would work for you as well.Hope this helps. It was the best investment I made as a dog owner.

I have a 45 pound border collie and bought the medium pack and it fits just right.

The medium size was perfect for my 55-60 pound lab mix mutt. He's a lean build and all muscle. The chest size table on the info page is very accurate.

My dog is almost 30 lbs but a frenchie so he is broad. The Medium fit him with a little room. Tough call, good luck!

a medium carrier might be a little tight, depending how long your pup is. the heighth should be ok.

My dog is 33 inches and growing. He has the Medium with room for adjustment to spare.

You should have no problem I have the next size larger for my 75 pound pitbull and he fits in there no problem so you should be good

I have a medium that I use as a travel crate for my 55 lb lab.I originally ordered the large but it is huge.

I have a 45lb American Pit Bull and the large fits her. Since bully breeds can sometimes have wide chests, I measured my dog's chest girth, neck, and back then went to the Outward Hound website to look at the sizing chart to find the best size. The website says the chest girth is the most important probably because the chest straps have the least room for adjustment. Good luck! It's a great backpack :-) http://www.myoutwardhound.com/2490.html

Medium worked perfectly for my 50lb Australian Shepard. I assume that Medium is what you need.

My dog is @39 lb, 17-18" length and 27" girth. The Large was much too long but fine around the girth. I exchanged for the Medium and the length is perfect but too small on the girth. So I think the Medium would probably fit your pooch perfectly.

I bought a large for my 60 lb. American Bulldog. I'm not sure if that helps but it had plenty room. If it were me I would get a medium to be safe.

I ordered a small for my 19-pound beagle-mix and it fits fine. The medium might be too big for your pup.

My dog is 58lbs and the xl fit just fine. I have an adult greyhound, and you have a doodle puppy. Good luck with your choise! Barb

I think a medium will still be fine. My pups are 10 and 12 lbs and it fits theirs bellys fine.
