FAQ
How long does it take for a dog to lose weight?
Most dogs can safely lose weight in 2-6 months, depending on how much they need to lose.
Can I just feed my dog less of their current food?
Not recommended. Weight loss formulas have fewer calories but maintain essential nutrients. Simply feeding less may cause nutrient deficiencies.
Should I exercise my dog more while dieting?
Yes, but start gradually. Overweight dogs may have joint issues. Consult your vet for an appropriate exercise plan.
