I have a 2 month old chihuahua and i saw that he was weak yesterday. He couldn't stand up at all and couldn't lift his head. I ran to a pet shop which had a vet present and she told me that the dog had "sugar shock". She gave me a bottle of nutri cal and started feeding him it through a syringe. I saw his eyes opened up a little and he began to regain strength but then in the night I was scared because all he was doing was sleeping. I went to the vet and left him there over night and they told me that he was fine and they gave me some antibiotics and told me to feed him nutri cal only when he isn't eating. Today the same thing happened he stood up and drop to the floor of his cage and i rushed and fed him nutri cal. He seems fine now but my question to you is how many hours a day and should I give him the nutri cal? I really love my dog and don't want nothing bad to happen to him.
