My dog is champagne Teddy. It is very small. I heard it's a toy type. It's almost three months now, 2.5 kg. How old can you grow as an adult?

According to the information you provided, your Teddy dog should be a toy Teddy dog. This breed of dog usually weighs 4-6 pounds and is no longer than 10 inch. However, every dog has individual differences, so how big your dog can grow into an adult still needs to consider some other factors, such as heredity, nutrition, health status and so on.

Generally speaking, the development process of Teddy dogs is slow, and it takes more than one year to fully mature. In the puppy period, Teddy dogs need good nutrition and proper exercise to promote healthy growth. I suggest you consult a veterinarian to find out how to provide your dog with proper diet and exercise to ensure its healthy growth. At the same time, take the dog to the vet regularly to ensure its health.
