At least twice a year my dog, a white lab/pitt mix loses weight and looks horible. He is 9 years old and still as active as a puppy. My other dog a yellow lab doesn't seem to have this problem. I have taken him to vets but nobody has ever found anything wrong with him. Do you have any idea as to what could cause this? Also one of his canine teeth looks to be reddish in color, What would this be?
If the vet said that everything is ok, then it probably is ok. I would not be concerned about this if your pet gains the weight back again. I would be more concerned if the weight stayed off. Some dogs will lose weight in the summer b/c of the changes in the weather. Maybe the root of the tooth is dead. Good luck, vetcrae
