Hi everyone, just after some advice. I have a 7 month old patterdale pup who's normally really active and healthy and happy. I feed him on baker's puppy complete dry food which he loves and seems to have been thriving on, but yesterday I went to give him his tea (about 4.30pm) and he was taking ages to eat it, and then after finally managing to get it all down he threw it all back up again and has been vomiting ever since (16 hours now). He keeps trying to drink but every time he gets some water down he promptly brings it all back up again. He's very lethargic and just generally not himself. Does he need urgent vet attention, or has he just picked up a bug or something that will pass? I'm really concerned that he hasn't managed to keep down any fluids for 16 hours. Any advice greatly appreciated, thanks.
