Regular chihuahua how big does it get and would you know if is a mixed breed because your dog 4 months his ears are not standing up?

It's great you're curious about your pup! Here's some information:

Size:

* Regular Chihuahuas: Typically reach 6-9 inches tall at the shoulder and weigh 4-6 pounds.

* Teacup Chihuahuas: A smaller variety, often under 6 inches tall and 4 pounds.

Ears:

* Ear Flop: A Chihuahua's ears are generally erect (standing up) by the time they are 4 months old. If your pup's ears are still floppy at this age, it's possible:

* Breed: He might be a mixed breed.

* Cartilage Development: Some Chihuahuas have a slower ear cartilage development.

* Genetics: Certain bloodlines might be predisposed to floppy ears.

Mixed Breed?

* Other Traits: Look for other physical traits that might indicate a mix, like:

* Size and weight: Larger than average for Chihuahuas?

* Coat type: Different than the smooth, short coat of a Chihuahua?

* Other physical features: Longer legs, a different tail shape, etc.

* DNA Test: The most accurate way to confirm a breed mix is with a dog DNA test.

Important Note: While floppy ears might indicate a mix, it's not a guarantee. Some purebred Chihuahuas have floppy ears due to genetics.

Enjoy Your Pup! No matter his breed, your pup is special!
