I have a 2 1/2 year old long coat GSD. He was a very picky eater when he was a puppy, but had a ravenous appetite from 6 months to 1 1/2 years old (when he was doing the bulk of his growing). Since last summer he has been extremely difficult in the feeding department. He has never been fed table scraps only given liver treats when doing training. He has always eaten at the same schedule from 8 weeks old, which is 6:30am & 8:30pm M-F, 8:30am & 8:30pm Sa-Su. He is currently being fed Natures Variety Instinct Dry Dog Food with 2 TBSP of Tripett Venison Tripe. The tripe solved the eating problems all through the winter and spring, but for the past two months it has made no difference. He will eat if coaxed (we tell him to go back to the kitchen to eat) some of the time, but will refuse at least one meal a day...he's averaging only 3 cups of food a day when he should be getting about 5. He is underweight as it is and we are trying to put weight on him, but that's not going well with him not eating. We have tried picking up his meal after 15 minutes or so and not feeding him until the next meal...here's what he does: he will refuse the meal...we take it up...he will eat the next meal...we feed him the next day and he refuses...we take it up...he will eat the next meal...still not getting enough, but eating enough to get by...what do we do? Don't tell me to switch to RAW...I want to but I am doing research first...I want a solution to the problem at hand.
