I brought my 2nd sack of vitality about a week ago. This week they were sick with fever and vomiting and one of them really got confined sa clinic. The other one stayed sa haus as she was not that critical. My problem is they are not eating anymore of the vitality food i am giving them. So i gave them table food just to have something to eat and some hotdogs which they really like. I'm happy they have the appetite back but they seem to be 'afraid' of vitality. My dogs must have associated the food with their sickness, do they have that type of thinking like humans?..
