The first thing you need to do when your dog gets too big is get him checked out by a veterinarian. If he’s not eating, drinking or urinating normally then it means something is wrong with him. A vet will examine your pet and make sure everything is okay before they give you any advice. You’ll probably have to pay for the exam yourself, but if you’re lucky, they might even refer you to someone else who does this kind of work.
If your chihuahua is obese, he may suffer from health issues such as diabetes mellitus (kidney disease), heart disease and other medical conditions. Obesity can cause arthritis and joint pain in dogs. They can develop kidney failure and die from complications due to obesity.
A chihuahua weighing over 40 pounds (18 kg) is considered obese. A normal weight for a chihuahua is between 14–20 pounds (6–9 kg). A healthy adult male chihuahua weighs around 20 pounds (10 kg), while a female chihuahua weighs around 16 pounds (7 kg).
Even though most pet owners think their dog doesn’t need a lot of exercise, this is not the case with chihuahuas. They are very energetic and require a lot of exercise. They have lots of endurance but don’t deal with heat well so you can’t exercise them for long periods in hot weather. A short walk or play session in the yard once or twice a day will meet their exercise needs and keeping them on a good feeding schedule will keep their weight in line.
