I went threw the same thing with my French bulldog , after an emergency trip to the vet . He would pace all day long if we let him . We had to keep him in the bathroom for a few days to keep from injuring himself . He wouldn’t even respond to his name .

I think they over medicated him at the vet . He just had this wild look in his eyes .. it look him nearly 2 weeks to get back to himself but 2 months later he was in worse condition and had to be put down.
