I have a 4 yr old large breed mix and a 2 yr old Lab. Murphy has Cushings and has had surgery on both of his knees. Stormy(Lab) is true to her name. She does not know how to slow down. The surgeon would love to see Murphy's weight down to around 90lbs. He currently is at 106. Stormy could stand to shed a few pounds herself. She is at 79lbs. I am feeding them Blue large breed 2x a day. They get about 3 cups daily each. I do limit treats. It seems that no matter what I do, Murphy can't shed any weight. We walk at least once a day for about 30min. Because of his knees, Murphy is not able to play like Stormy. He does play some. I've had his Thyroid checked and it is in the normal range. They both are on fish oil and gloucosimin(sp) supplements. I have tried switching to the weight control. It made no difference. I do like the large breed formula, because it has the extra supplements. I'm hoping to not switch brands again. They love Blue. Any advice is very much appreciated.
