My yorkie's name is Bruiser and is already 7 lbs. at a little over 4 months. His mother is 4 lbs. and his dad is 6 lbs. I am concerned about him gaining too much weight.
He goes for a run with my son every day after school, and we play fetch throughout the day along with training about 3 times a day.
I feed him
Iams® ProActive Health™ Smart Puppy Small & Toy Breed 3 times a day 6 am, 1 pm, 6 pm and don't leave the food out for him. If I use low fat treats or his dog food for treats during training I skip the 1 pm feeding. I put out approx. 1/8 cup of food each time and sometimes give with carrots and apples. When he doesn't eat, I simply take the food away after 30 minutes and try at the next meal.
He does go poo approx 30-60 minutes after his meals, this is why I do not get concerned when he doesn't eat.
He doesn't appear to be overweight and is quite tall for a Yorkie, although I haven't measured him. The vet says he is very healthy.
On a good note potty training seems to be taking after I had him neutered approx 10 days ago.
Thanks!
