I have a 20-lb Cockapoo. Any ideas on whether a small or medium would be a better fit?

I have a 20lb jack Russell and I bought a small fits good he was able to get the medium size off. Small fits snug but not tight.

I'm sure a medium would be fine. My poodle is at 17 lbs. and I have a small aerodawg. It works perfectly. It only has to cover the snout.

I'd go with the "small". Our 21 pound Bichon fits comfortably in the medium, which takes quite a bit of room in the back seat. Your dog is probably 1/2 the size of ours. Petgoods carries these (at a higher price); you could go check them out if there's one near you.

I have an extra-small for my 4 lb. yorkie and a small for my 6 lb yorkie. A medium should be ok. A snug fit is much better than a loose fit.

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

I got a large for my 20 pound Peke. It is very large for him. But it's his little home, so.... A medium would probably do, but Teddy has lots of space to turn around and play. Hope this helps. I was also wondering and when it arrived I felt it was TOO big. It will be a problem for traveling. Even folded up (which appears to me will be a little difficult, it is large.

I bought this for a dog that weighs approximately12-15 pounds. I think the medium would have plenty of room if you wanted to add a blanket or something. But I would assume the smaller one would work better.

I had the same problem with my dog and I went with the medium. No problems so far and the straps are generous so if you're an inch off either way it wouldn't be a big deal.

It should be okay, def smaller than I expected but I think a 20 lb dog would be okay if not too long or overweight, not sure what kind of carrier you have, very round not oblong....

I have a 16 lb. Havanese and I bought her a small. There are adjustments so your Shorkie should easily fit into a small without being too big.

At 28lbs, either ThunderLeash should fit. It will ultimately depend on which size feels more comfortable for you and your pet, as the Large is much heavier than the Small. You could also try the Medium Retractable ThunderLeash, which would probably provide a more comfortable fit.

I bought the medium and my pit bull is small with a 25" girth. I have extra strap hanging off. You should be (at most) fine with what I have left hanging.

The one i got was for up to 20 lbs my problem is that my 13 lb dachshund is too long now,i would think a cockapoo would be shorter and should fit.

I have a 17-20 pound Welsh terrier and the medium was a perfect fit. We originally bought a small based on the Thundershirt sizing but that was about 2 inches short on his back and too snug around his chest. Hope that helps.

I use a Medium for my Corgi mix who weighs in low 30's. I haven't seen a small one, so I'm not sure how much smaller a small really is but you might be ok with a small, definitely ok with a medium

Sorry to just respond. I have a pitbull mix (about 75 pounds with a chest measurement of 28 inches). We ordered a medium and it fits well when the straps are all-the-way tightened. Not sure what's best for your dog. If your dog is full-grown, then probably a small.

should do well with the medium or large size. I have a Lab, Golden and a Basenji, all three do well with the large size.
