how old is the dog, what breed...what type of food.
Score loses weight substantially in the spring...he eats a certain amount during the winter, and he exercises heavily throughout the winter (sproinging through 2 feet of snow helps with exercise!
Come Spring, he has to go up at least a cup of food for a while...as his body adjusts...and you can count every rib and vertabrae...it's sad to look at for a while!
Looks like a neglect case (except for the muscle)...since he doesn't have much to lose in the first place.
He normally eats 2 cups of Extreme Athlete food...high protein/high calorie food...this spring, he's gone up to 3 1/2 cups of the same food, to get some weight back on.
