Pet's info: Dog | German Spitz | Male | unneutered | 1 year old

What are the main health issues young dogs face? My dog is 1, and seems to be losing weight and drinking excessively. I just wanted to know what it's likely to be and whether it's serious or not.

Young dogs are usually very healthy and do not commonly have issues like excessive drinking and peeing. These can be signs of an underlying issue like diabetes, Cushing's disease, or a urinary tract infection. Since Paco is showing some abnormal symptoms I would recommend taking him to your vet. Hopefully there is no major issue going one and Paco just likes to drink a lot of water. Good luck.
