From puppy or kitten to adult: When to shift your pet's food?

Puppies and kittens have different nutritional needs than adults, because they require higher levels of protein, fat, and specific calcium and phosphorus contents to support their rapid growth. Transitioning to adult food too early can deprive a young dog or cat of the essential nutrients they need for proper bone, muscle, and immune system development. On the other hand, continuing a puppy or kitten diet beyond the growth phase can lead to excessive weight gain and a nutritional imbalance, potentially causing health issues like joint problems or obesity.

Therefore, timing the switch based on your pet’s breed and growth stage is crucial for maintaining their optimal health and supporting a smooth transition into adulthood:

- At 12 months in kittens (15 months in Maine Coons),

- At 10 months in small breed dogs (less than 22 pounds / 10kg adult body weight), except for Chihuahuas and Pomeranians, who should transition at 8 months,

- At 12 months in medium breed dogs (between 22 and 55 pounds / 10-25kg adult body weight),

- At 15 months in large breed dogs (between 55 and 99 pounds / 25-45kg adult body weight),

- Between 18-24 months in giant dogs (> 99 pounds / 45kg adult body weight).
