Is a dog full grown at 10 months?
Small breeds such as Cavachons or Shorkies are nearly fully grown at 10 months old. Large breeds are not – in fact, some very large dogs such as Mastiffs or King Shepherds can grow and fill out until after their second birthday.
At what age does a dog reach its full height?
Small dog breeds reach their full height by their first birthday. Large dog breeds can grow in height until they are about 16 months old. But even after that age they will continue to “fill out”. Their chest can become wider (especially if they have not yet been spayed or neutered) and they become more muscular.
If you own a long-coated breed you will notice that your dog’s coat continues to grow and become more voluminous. This might give your dog the appearance of growing considerable, but it is all fluff!
Do dogs eat less when they stop growing?
Many dogs eat a lot while they are growing, especially giant breeds. Their calorie needs decrease as they reach their final size. You will probably need to adjust your dog’s food once he reaches his adult size and weight. (Just like a growing teenager eats more than most adults!)
If you notice that your dog gains weight and becomes chunky somewhere around 18 months of age, the reason is probably that he does not need the amount of food anymore he required as a growing puppy.
