I have a shepherd mix so I purchase the X-Large size as noted on size chart. They barely fit past his butt which defeated the purpose of buying them, when he pees he still gets all wet because the diaper doesn't cover that part. The tabs wouldn't stick well they kept coming off by the mornng the diaper was totally off. Am returning and will tell and wouldn't recommend for anyone!
This product works very well for our older, incontinent dog. The velcro has been improved so the diaper can be adjusted multiple times. The pricing on this site is also great, but the delivery time is unacceptable. Expedited shipping appears to be available but is not and it takes far too long to arrive, at least in PA.
