Pooh Bear, our 8 year old sweet male has been letting out a yipe about once or twice a day. The first time he did it about a week ago, I was walking close behind him and he yipped and looked up at me. I thought I had accidently stepped on his foot and apologized to him and petted him. But he has done it more. He can be just standing or walking along, and yipe. Just one yipe, and then he is fine. I've examined his feet, his nails are way long and I'm wondering if a nail is bothering him. He is walking fine, no limping or slowness. Or what is it?? I'm making him an appt. to get his nails clipped, his anal glads done and an exam.
