As a consequence of the care we provide to our pets, they live longer. A dog or a cat is considered old when they reach 8-10 years of age, depending on the breed. It is recommendable to carry out general controls of the most frequent senile pathologies. Carrying out a cardiologic control, blood and/or urine tests and a detailed clinic and exploratory evaluation will help us detect these pathologies and stop their progression at the earliest possible stage.
