When do Halden Hounds stop growing?

Halden Hounds stop growing at around 18 months. While they’ll reach their full height by a year old, most will continue building muscle until around 18 months. You’ll want to transition them to adult food around their first birthday when their rapid growth is completed and their nutritional needs switch to a less calorically dense and lower protein diet.

To safely switch them over to adult food, it’s best to transition gradually over a week. Start by mixing about 25 percent adult food with 75 percent of their current puppy food for a couple of days. Then, move to an equal blend for another two days, followed by 75 percent adult food and 25 percent puppy food. By the end of the week, they should be fully on adult food. This slow transition helps avoid digestive upset and lets them gradually adjust.
