Rat Terrier Puppy Feeding Schedule
Age-by-age feeding guide for Rat Terrier puppies — from 8 weeks to adulthood
Rat Terrier puppies may be small, but their nutritional needs per pound are higher than larger breeds. Small breed puppies have fast metabolisms and limited glycogen reserves, making them susceptible to hypoglycemia (low blood sugar) if meals are missed. Feeding your Rat Terrier puppy requires small, frequent meals of calorie-dense food to maintain stable blood sugar and fuel their rapid early growth. Most Rat Terrier puppies reach adult size by 9-12 months, which is earlier than larger breeds.

Puppy Feeding Tip
Building Strong Joints from Puppyhood
Since Rat Terriers are predisposed to joint issues, the nutritional foundation you build during puppyhood matters throughout your dog's life. Proper nutrition during the growth phase can reduce the severity of inherited joint conditions and delay onset of symptoms.
During Growth (puppy)
- Controlled calcium/phosphorus ratio
- DHA for cartilage development
- Moderate calorie intake (avoid overfeeding)
- Large-breed puppy formula with joint support
Into Adulthood
- Glucosamine and chondroitin supplements
- Omega-3 fatty acids (EPA/DHA)
- Maintain lean body weight
- Consider foods with added joint-supporting ingredients
