I think our Bingley has OCD. In his first year he licked himself to such an extent that we had to put him in the hospital several times. He adopted a different obsession thankfully, and became obsessed with plush toys. Rarely does he not have one in his mouth. He likes to push them at us so we will play catch with him. Yesterday he started coughing for several hours, and I know it's the plush toys. So, I took them away and bought him a bunch of rubber toys, all which he rejects and does not like. Breaks my heart to withold his cherished and toys that comfort him! I'm going to ask the Vet about whether there are meds for his OCD.
