Cavaliers and Heat Tolerance

As the summer months descend, many pet owners worry about the safety of their pets in the heat. Cavaliers, in particular, have a reputation for being a breed that needs extra attention when the temperature rises. But how hot is too hot for Cavaliers?

Cavaliers are a small breed of dog originally bred in England. They have long, silky fur that tends to trap heat, making them more susceptible to heat-related illnesses. Cavaliers are also known to have a low tolerance for high temperatures. In general, anything above 80 degrees Fahrenheit can be too much for them to handle.

Signs of Heat Stress

When panting does not help a Cavalier cool off, there are a few signs that indicate the dog is overheating. These include excessive panting, red or pale gums, and fatigue. If any of these signs are present, it is important to take the dog inside and cool them down immediately.

Preventing Heat Stress

The best way to protect Cavaliers from the heat is to keep them indoors or in the shade during hot days. If the dog must be outside, make sure there is plenty of water available and keep a close eye on the temperature. If the temperature is too high, it is best to bring the dog inside as soon as possible.

Additionally, it is important to provide plenty of access to water when the dog is outside. The water should be changed frequently to ensure it is cool and fresh. It is also important to keep the dog well-groomed, as this will help the fur to insulate the dog against the heat.

Additionally, you can purchase cooling beds or mats for your dog to lie on. These can help to keep them cool, as well as comfortable.

For extra protection, you can use a cooling vest for your Cavalier. These vests are designed to help keep the dog cool by absorbing heat from the body. Additionally, it is important to keep the dog active during the cooler parts of the day, such as the early morning or late evening.

Finally, you can offer your Cavalier ice cubes or frozen treats. These can help to cool the dog down and can be a fun treat.
