O.K., I'm hoping someone can help me.....I have a 5 y.o. female Chesapeake Bay Retriever that I hunt for both duck and upland. The problem I have is that when she runs, the first toe nails on her back feet rub against her 2nd toe and creates a nasty abrasion, causing her to come up lame. Dog boots don't work, as the toe still rubs against the nail while in the boot. Has anyone ever had a similar problem? She is usually out for 3-4 days after hunting upland, and I'm thinking about getting a second dog just for hunting upland (which is going over like a lead balloon with the wife). Any input that could help me with the problem would be appreciated. Thanks in advance.
