Does their heart size affect their personality?

Some believe the large heart contributes to Chihuahuas’ energetic and sometimes sassy personalities. While there’s no scientific evidence to confirm this, their big hearts undoubtedly fuel their big personalities!

Are Chihuahuas prone to heart problems?

Unfortunately, due to their unique anatomy and heart size, Chihuahuas are more susceptible to certain heart conditions like mitral valve disease and tracheal collapse. Regular vet checkups and a healthy lifestyle are crucial for keeping their hearts happy and healthy.

Keeping Your Chihuahua’s Mighty Heart Happy and Healthy

Chihuahuas may be tiny, but their hearts are huge! But with a big heart comes big responsibility. These pint-sized pups are susceptible to certain heart conditions, so keeping them healthy and happy is vital. Here are some simple tips to ensure your Chihuahua’s heart stays strong:

  •  Keep them at a healthy weight. Obesity puts a strain on the heart, so maintaining a healthy weight is crucial. Talk to your vet about your Chihuahua’s ideal weight and stick to a portion-controlled diet.

  •  Brush their teeth regularly. Dental hygiene is surprisingly important for heart health. Plaque and bacteria from neglected teeth can enter the bloodstream and damage the heart valves. Brush your Chihuahua’s teeth regularly to prevent this.

Just like humans, dogs communicate through their eyes. Soft, sustained eye contact with your Chihuahua, especially when accompanied by relaxed ears and a wagging tail, is a sign of deep connection and trust.
