My old ACD, Smack, broke his leg after being kicked by a zebu calf. For some reason, the vet put a bright pink cast on his leg, just like hers. He was miserable, especially while he was outside. We had to tie a grocery bag around it. It almost seemed like he was actually embarrassed, LOL.
Poor baby. At least it sounds like everything is getting back to somewhat of a normal place. Its hard keeping them slowed down when they have a cast. Two of mine have been in casts and the little one would hold her leg out and run with the other two. She could fly with that cast on. lol! What was really funny, when she had it took off, she still held her leg out to tee tee. It took awhile for her to realize it wasn't there anymore. Hope your baby gets along well. Like that hot pink.
