Buddy is a solid big boy weighing in at 40lbs. I love the big mush to pieces!


We have a large Boston that weighed 38 pounds when we got him at age four. Now he is 28 pounds and is much healthier.


Our two litter mates are 4 years old now and weigh 35.5 lbs. and 37 lbs. They are tall, long, trim and athletic. Pure muscle and strikingly handsome.

My 4-year old spayed BT weighs 30 pounds. She looks like a deer with her long legs. She runs so gracefully and is ALL muscle!

18 lbs at last vet check.


Luna is best at 20 lbs. She can put on some pudge in the winter. She gained 3-4 lbs so I reduced her meal size for the inactive periods of winter. She has luxating patella’s so any extra weight is hard on her little knees. Trying to avoid surgery and 20lbs is the perfect weight for her. My previous girl.
