He hit his tail and wounded it. Infection set in and it inches up his tail. His tail is dying and at times he ate his own tail off. The vet said there was no saving it at this point and they cut it above the infection. I'm going to have a 10 year old lab with a bob tail.
Not sure what cold tail is
Dang that sucks. I think a lab with a bob tail would look pretty cool. I like bob tailed cats better than normal cats.
Cold tail is just a muscle strain that usually goes away in a few days.
