My 3yr old female mixed Lab(she is fixed) has been licking her butt constantly for awhile - she leaves wet spots on the rug when she does this. Also she only eats her dinner 2-3 times a week, the rest of the time her food sits until I throw it away. Is there something wrong with her that she should go to the vet for?
It sounds like your pet may have impacted anal glands. This can be a painfull condition and I recommend that you take your pet to the vet. Good luck, vetcare
