Generally, Chihuahuas are considered puppies until they are 12 months old. Puppies typically grow rapidly and will often reach their full adult size by the time they are 1 year old. However, some Chihuahuas may continue to grow slowly until they are 2 years old.
If your Chihuahua puppy is 7 pounds 4 ounces at 9 months old, he is likely to be at the larger end of the weight spectrum for his breed. He may reach his full adult size by the time he is 12 months old, or he may continue to grow slowly until he is 2 years old.
It is important to keep in mind that all dogs are individuals, and your Chihuahua puppy may grow at his own unique rate. If you have any concerns about his growth, be sure to talk to your veterinarian.
Factors affecting chihuahua size
- Genetics: Chihuahuas come in two main size variations, the applehead Chihuahua and the deerhead Chihuahua. Appleheads tend to be smaller, with an average weight of 3-5 pounds. Deerheads are typically larger, with an average weight of 5-7 pounds.
- Gender: Male Chihuahuas are generally larger than females, with an average weight difference of about 1 pound.
- Nutrition: A well-balanced diet is essential for healthy growth. A Chihuahua that is undernourished or overweight may not reach its full potential size.
- Exercise: Exercise helps to build muscle and bone, which can contribute to a Chihuahua's overall size.
- Overall health: A Chihuahua with underlying health problems may not reach its full potential size.
To ensure that your Chihuahua puppy reaches its full potential size, it is important to provide him with a healthy diet, regular exercise, and routine veterinary care.
