Hey i have a 11 week old husky before he was eating 3 times a day now he doesnt even want to eat at all also he isnt as active as before and last week he was vomiting and had diarrhea .. does anyone know why ?

As I said in the reply to your other post, take him to the vet.
Those are serious symptoms for a puppy. He could be ill, or he could have a blockage in his digestive track. He needs to be seen and treated by a professional ASAP.

well he threw up last week but when he trew up after the third time he threw up a small piece of a plastic bag . which i think was the reason for him throwing up. and well before throwing up he has ate his full bowl of food like normally. i feed him 3 times a day . but after that he wont eat but only once or twice. he will now eat just half of what he used to eat . and well im not saying hes down like he wont move from one place but he was normally very hyperactive and well now hes not as much . i have to look for him and catch his attention for him to want to play or do anything. he has had 7 of his shots and has been wormed twice .. he hasnt been around much dogs because i was told to keep him isolated. only 3 times hes been near other dogs but its when ive taken him out to the park to play i feel bad having him only in the house. i didnt think it would harm him. i feed him purina puppy chow. thats what the breeder that i got him from recommended me but now he seems to not like it so in the pet store i was recomemded a can of the wilderness puppy food i give himt he chicken and turkey flavor. i try to give him apples because he would like them but now he wont eat them . i saw online they are very picky . one day he likes a food the next day he wont. but im unsure...... does this information help out ?

Dayanna, it would help us immensely if you would post to just one thread. I'm off to respond in your other one.
