Any ideas why my dog is panting and shaking? She normally eats dog biscuts and We dog food for breakfast. This morning I gave her some raw chicken, about 200g for my little chihuahua (sp?) She was fine earlier, but around 5ish she started getting really nervous. She's had a HUGE poop, which came out lighter in colour than normal, and she's been panting heaps, staying still. She's jumped at shadows a couple of times (strange). She's had a little drink of milk, now she's not panting like mad, but she's still shaking. Does it sound like something in the chicken? It has unfortunately been frozen, thawed, and refrozen, and then rethawed before she got it. Could that have something to do with it? BTW, she's about 9years old.
