Query: Don't buy Muttluks

I purchased the Muttluks all-weather boots and am very unhappy with them. I bought them for my 62 lb. Golden Retriever who gets very muddy running in the backyard. The first time I put them on her she ran after a possum and when she stopped the front boot came off along with ripping off her dew claw. I was very upset over this happening. She had to be on antibiodics for 2 weeks. I spoke to Muttluks office and they told me this has happened before. For some reason they have not fixed the problem.
