hello everyone. has anyone ever experienced a lop-sided puppy? my 6 month old seems to have a dropped left side (at the front) and walks unevenly. it has caused her pain in the past, and i've taken her to the vet but it is inconclusive. she is due to see a specialist next week and we will probably have her x-rayed but I just wanted to see if anyone else had experienced this? thank you.
