Hi all. Last month and again this month my 8-month-old pup has been moaning and can't get comfortable, she lays down for about 10 min, cries and gets up and tries to lay somewhere else, but also eats grass and sometimes vomits. Is it possible its growing pains and the pain cause nausea which makes her vomit? I've been to the vet 4 times in a month, blood work, all organs fine, urine test to double check kidnets, all fine. Considering ultrasound if it carries on.
