My dog was fine all day yesterday and last night until bedtime. He suddenly acted as if he could not jump up on the bed ( where he always sleeps ) but finally did so for a treat. Sometime later in the night he moved to the floor and slept the rest of the night there. He has NEVER slept on the floor since we’ve had him. This morning, he does not want to move – very lethargic. He will take a treat but very slowly ( he is extremely, extremely food motivated and excited by any/all food ). He did finally walk down the stairs at an extremely slow pace. He does not want to be picked up and just really wants to lay there. I’m going to see if he wants to eat breakfast ( it’s typically the NUMBER ONE thing on his mind as soon as we come downstairs but he is just laying on the rug sleeping. Should I see how breakfast goes and assess from there ? See how the day goes? My vet is open from 1-3 today but I’m not sure that’s for appointments for sick pets. I can always go to the ER if he doesn’t improve or call JVET first thing in the morning if there is no improvement ??? Any advice?
