Shih tzu nit carrying his tail
Hi yesterday after dinner my 8 yr old shihtzu dropped his tail and went very quiet
He slept well and has had a walk today ( tail half way up and trying to wag but not normal carriage for him) he was lively on his walk and did a slightly constipated poo but is weeing ok.
He's eating well but just really quiet .
He had a slipped disc in his cervical spine 2 years ago which he has fully recovered from, just not sure how long I should leave him before taking him to the vet because of this tail issue? I have metacam but am not sure if he needs it...
