My Sam is 8 years old he just started last night licking the furniture
Pillows, the air, me. He did this through the night. I gave him
Some Benadryl thinking he was having an allergic reaction because he seems
To be swallowing hard. 4 hours later He has slowed down a little with the licking and is swallowing fine but is still Licking everything. This is out of character for him. He has recently visited the vet and has a fatty tumor besides that he is healthy. What is going on should I take him back to the vet again?
