Transition Instructions

We recommend at least a 7 day transition before you begin feeding the new food exclusively. Start by mixing 75% of the old diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the old diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the old diet with 75% of the new diet. On the 7th day, you can feed the new food exclusively. This allows your pet’s digestive system to smoothly adapt to the new food.

  • High Hopes

    By on

    I recently switched my 16 year old toy chihuahua to this food in hopes that it would be helpful on his aging process. So far, he has been on it for two weeks. He eats better than he did previously and I've noticed an increase in his energy levels and a brighter disposition. The brown age staining around his mouth, eyes and forefeet has lessened considerably. He also has had easier bowel movements. All in all, I'm extremely hopeful. Previous food he was on was Merrick for comparison. My old man will not be going back to it after doing so well on this for 2 weeks.
