@alexbaba:
i just started having the same problem with my 4 month old pure bread "B". any advice? i feed him 2 times day 1 cup morning and night and he has only been eating 1/2 a cup. he ate a diffrent brand dogs food a few days ago at a friends house but it was only 1 bit. could this be the problem?
Maybe you should try feeding him 3x a time until he's a little older. Try giving him 1/2 cup in the morning, 1/2 cup in the afternoon, and 1/2 cup at night.
See if that helps with the vomiting.
I wouldn't be concerned myself if my 4 mos old puppy wasn't eating a whole cup of food at one sitting. He may just be self-regulating.
Jazzy is 3 yrs old and won't eat more than 1/2 cup at a sitting. She knows her limits.
Neither of my two B's would have eaten 1 whole cup of food at one sitting at 4 mos old. I started them both on 3 feedings of 1/2 cup a day and worked them to 2 feedings by about 6 mos.
My adult B's eat – Well, Jazzy eats about 1 cup of food a day {1/2 cup twice a day} plus treats, Keoki { 14 mos} eats 1 3/4 cups of food a day {1 cup in the AM, 3/4 in the PM} plus treats.
