How Big Will My Puppy Get?

Your Dog’s Weight Category:

According to the weight of the puppy measured at various intervals of time, the overall weight range of different dog types is listed in the following table below:

Toy dog	< 12 lb / < 5.4 kg
Small dog	12 - 22 lb / 5.4 - 10 kg
Medium dog	22 - 57 lb / 10 - 25.9 kg
Large dog	57 - 99 lb / 25.9 - 44.9 kg
