Hi! My dog has recently been licking around is butt and has completely licked off the hair on the back of his tail. He’s been doing it for about 2-3 weeks now. I thought it was the new food I tried with him but after seeing him do it for a few days, I stopped and went back to his original food. However, he has not stopped and now I’ve notice my other dog biting around her tail a little. Not nearly as bad as my male dog though. I am concerned something else is going on like worms. I unfortunately still owe a lot of money to my current vet for emergency visits the dogs had early this year and can’t afford to take them in to be checked. Can I try using Safe-Guard with them to see if that corrects the issue? Is something else possibly going on?
