7 wk boxer pup unwell

Question
i have a 7week old boxer pup who is not drinking any fluid with diarrhea but is still eating. i have only had her for 24hrs. breeders have had her wormed and first jabs they were feeding her winalot but i have changed this to puppy science plan is this the problem

Answer
Hi Sarah. This may be the start of coccidia. I would get her to the vet fast. If it is coccidia, the vet will give Albon, and the pup will feel better in a day or so. You have to act fast with such a young puppy though, coccidia can kill. Changing food fast can cause diarrhea, but since she's not drinking as well, your best bet would be to get her to the vet. Science Diet isn't the best food out there, you may want to reconsider what you feed her.
