Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 11 years and 9 months old
Hi there! My 11-12 year old terrier mix drinks a lot of water. Is it normal for an older dog to do that? He is the same weight he's always been 12 lbs. and still has good energy for his age. He eats Purina Pro Plan and his appetite is normal, but in the morning, or anytime he goes for his water bowl, it like he's been without water for days. He drinks it voraciously. Thank you for the info.

Am increase in thirst or urination, especially in an older pet, may indicate a degree of kidney disease. Other potential causes include infection and behavioral issues (psychogenic polydipsia). As long as he is behaving normally, you can wait to see your veterinarian. Schedule an appointment in the morning. Your veterinarian may recommend blood work to assess major organ function. Afterwards, xrays of the abdomen or an ultrasound may be done to further assess the kidneys and bladder.
