Hello,
My 5 year old cocker spangiel got a hair cut on Tuesday morning while our new couch was being delivered. He came home and seemed ok...... in the afternoon he was barking at the door at another dog passing by and he might have hurt himself because he stopped barking abruptly. Now 3 days later he is breaking my heart!!!! He seems so upset. He would not get up this morning. I had to call "grandmom" to come over. He then went outside and seemed ok. His back legs are sometimes shakey but his is walking normal. Tomight all he is doing is pacing. Going around and around the table. When he finally sits he puts his all body into you. What is wrong????????????? Could the groomers have given him some kind of drug? Or worse, hurt him and he is remembering all what happened on Tuesday? We have had him all his life and he has never acted like this. Please Help!
