In the last one month my dog has been getting recurring stomach infection. Before this started ,she would eat Pedigree gravy (4 packets) and egg rice every day. Infection happened due to overfeeding. Now her diet has been reduced to Vet Pro Gastro food(half cup) four times a day and milk ( 4 tablespoons) twice a day. But today again she excreted some watery liquid after passing the stools. She is otherwise active but feels hungry every 4 hours as a result of which she tends to overfeed. But now her diet has been limited to gastro food .She is 15 years old. Her blood tests were also normal except for SGPT which was 113 (done 2 weeks back). Please suggest.
