Get Your Dog Care Questions Answered by Experts
What breed of dog do you have?
Did you bring the dog to the vet?
Why do you think the dog is paranoid?
Thank you for that information. Smaller breeds are prone to disc problems which can be misdiagnosed as a leg problem if the dog is limping. A disc problem in the lower spine will affect either the front or back legs but mostly the back. A disc problem in the neck will show more front leg lameness. Many dogs who have a problem do not want to be touched or held at times so this may be the problem. A regular x ray may not show a problem but a myelogram may need to be done.
For some dogs pain killers and muscle relaxers are not what they need but prednisone works better.
I would bring the dog back for a check up. The paranoia may be due more from pain and not wanting to be touched.
