I have a 2-yr old Standard Poodle who has be acting very tired all day today, seems like he can't get comfortable, won't eat, and just puked a lot. He did eat breakfast this morning and he got into the papertowels. He has been eating a lot of snow - with nothing apparant in it. About 2 weeks ago, he had worms which I treated and they stopped showing up in his stools. Please let me know if you have an idea.
