My vet has said that a dry/warm nose doesn't really mean a dog is sick. . it just means they haven't licked their nose

It's good that Peppy is feeling better! My BC starts to eat less often when the weather gets warm, I think he's just hotter and he's adjusting to the heat, then he gets his appetite back after the initial few weeks. If Peppy goes more than a day without eating (especially if he isn't drinking much water), and he seems sick to you, you should at least call the vet to get his/her opinion . . I hope Peppy is healthy and it's just his appetite!

also. . pictures of Peppy are welcome
