I have a 4-6 week old Togg cross wether. He had been doing fine, until yesterday he seems constipated. It started last night he would sort of squat and seem to strain but nothing would come out. He has continued this this morning. He has been eating about 500mls 3 times a day. He has hay available all the time and I offer him grain twice a day which he doesn't touch, He has not been wormed and does not have his shots yet. I called my vet about shots and deworming and since his back ground is mysterious the vet said to wait until the end of the month to give shots and worm him, since she said the shots would be useless if given before 6 weeks of age and we are not sure how old he is. She also said it wouldn't hurt to wait to worm him until he gets his shots. Could this be a symptom of worms? Any ideas whats going on?
