Not just for doodles or dogs under 15 lbs! work well for a 45-50lb pittie mix!
Was a little hesitant since every dog that uses this brand seems to be a doodle or another smaller sized dog and I have a dog on the larger side of "medium" that's a pittie mix. I am pleasantly surprised! His other harnesses had been rubbing against his armpits and his chest making his hair thin out there (and he isn't even a puller). This one has been doing wonder for helping that heal. I love how padded the harness is, as well as how many leash clips there are from different locations (most harnesses have the front and/or back clip, but not 2 back clips).
The harness is a soft and flexible material making it seems comfortable for my dog, but because its flexibility, giving me less control on the front clip for when he sees a squirrel.
Overall - great harness. Would love to see the padding to be sewn a little more study on the straps so they stay in place when he roughhouses withother dogs and when im putting it on and off. Otherwise, great harness, and would def reocmmend.
