My dog always trembles when he doesn't have an appetite in the morning - when he is hungry he'll willingly eat on his own. The trembling subsides after a while when I pick him up, but he still won't eat. His feces are usually hard and come out in little balls, or are a small amount. Sometimes he will also have a bloated stomach if the symptoms continue for several days. Our vet gave us probiotics the other day, but my dog's feces are still sometimes hard or sometimes a little soft. I hope he just wants attention... For pet food, I give him a mixture of Kia Ora and weight control food from Supreme, in the morning. I also give him bits of chicken breasts, yogurt, and natto. At night I give him soup with chicken breasts, salmon, and vegetables such as Chinese cabbage, carrots, broccoli, and radish. I give home soup because he doesn't drink much water during the day.
