How to take care of your pet

Caring for your pet is a responsibility that involves love, time and resources. Here are some essential tips to make sure your dog has the best quality of life possible:

Regular veterinary visits

Regular check-ups are key to detecting health problems early and keeping vaccinations up to date.

Quality food

Choose high quality food and make sure it is adapted to your dog’s nutritional needs.

Dental hygiene

Brushing your dog’s teeth and providing chew toys may prevent dental problems.

Regular exercise

Dogs need physical activity to stay healthy and happy. Daily walks and playtime are essential.

Weight maintenance

Control your dog’s weight to prevent obesity, as an obese dog can develop joint problems. Just like it happens to overweight cats.

Skin care and hygiene

Check your dog’s skin and coat for problems. It is important to keep it clean to avoid skin infections.


Dogs are social animals and need interactions with other dogs and people. Walks, visits to the park and playing with other dogs are important.

Training and mental stimulation

Keep your dog’s mind active through training and mental stimulation. This can help prevent behavioral problems.

Cuddles and love

Don’t underestimate the power of a good affection dose. Dogs need affection and attention from their owners to keep them happy.

Vaccination and prevention

Keep your dog up to date with vaccinations and perform regular check-ups to prevent diseases.

Safe environment

Maintain a safe environment at home, eliminating dangerous objects for dogs and avoiding access to toxic products.
