Apartment Friendly



Chihuahuas are intelligent and tend to bond strongly to one member of the household. This can lead to them becoming overprotective of that person so socialising with other people, pets and dogs from a young age is important. Due to their small size and delicate bodies they may be better suited to households without children or families with older children. Chihuahua’s can do well living in apartments as they are small, but they still need plenty of walks, play time and enrichment at home. Exercise is just as important for Chihuahuas as for bigger dogs to help avoid obesity.


There are short and long coated Chihuahuas. The short coated tend to shed more than the long-coated varieties so both benefit from brushing several times a week. Make sure your Chihuahua’s nails are not left to overgrow as this can become uncomfortable for your Chihuahua and makes it more difficult to trim them later. They can be trimmed with nail clippers. Prevent parasites by ensuring your Chihuahua is on flea and tick control all year round.


When choosing a food for your Chihuahua, select a premium food appropriate to your dog’s age and life stage. Get your Chihuahua used to eating biscuits from a young age to help encourage chewing and good dental health. Help prevent your Chihuahua from becoming overweight by ensuring that you follow the recommended feeding guides on the food appropriate to your pet's size. Make sure your dog always has a supply of fresh, clean water available.
