Query: Could nott keep them on!

I have a small terrier, and I wasn't able to keep the Muttluks on his feet. I had to keep turning around on our walk to search for one or two missing ones. I guess his legs are just too skinny, but I couldn't have possibly made them any tighter. I was hoping to protect him from the prickly things in the desert. I'm disappointed.
