How quickly should I expect to see weight loss results?
Hill's markets this formula around a roughly 10 week weight loss window, but actual results depend on your dog's starting weight, activity level, and portion sizes. Check with your vet for a feeding plan tailored to your dog.
Can I keep feeding this after my dog reaches a healthy weight?
Yes, the formula is also designed for long term weight maintenance, not just active weight loss, so many owners continue feeding it once their dog reaches goal weight.
Is this suitable for large breed dogs on a diet?
No, this formula is specifically sized and formulated for small and mini breeds. Large breed dogs would need a different Hill's Perfect Weight formula matched to their size.
