Hi
I have a 9 month old Border Collie Pup and we just can not get him tpo eat his dinner. He's very active and we've tried everything we can hink of, changing the food, feeding at same times, hot/cold, wet/dry etc the list goes on!
How on earth do I get him to eat. He'll go 4-5 days without eating. Its driving me nutsbecause he's a puppy so he needs his nutrition and surely he has to be hungry?
Please please help me

Check to see if his gums are white, if they are more than likely he has worms. When dogs have worms they tend not to eat. Are you sure he didn't get into anything he wasn't supposed to? Like swallow a big portion of a toy or anything? He could have something stuck in his intestine path. Does he go to the bathroom regularly? I would worm him first and if he starts eating good. If not take him straight to the vet.. Best wishes. I hope he is OK.
