Dog Housing tools: what they help with

These calculators size your dog's living space: the minimum and recommended dimensions, how much bedding or substrate to buy and what fits in the space you have. Too little space is one of the most common welfare problems in pets. The right size gives a dog room to move, rest and behave normally.

What to know about housing and enclosure size for dogs

Dogs live indoors with their family, needing daily exercise, mental stimulation, and a securely fenced outdoor area for larger or high-energy breeds. Target humidity is around 40-60%.

Treat the minimum as the floor, not the goal. Bigger is almost always better, especially for active or social species.
