When Do Chihuahua Ears Start Standing? Timeline & Care Tips

The Chihuahua is known as the smallest dog breed worldwide and is among the most cherished companion dogs in the United States. Their unique look and lively personality make them a favorite among American dog enthusiasts.

If you’re considering finding a Chihuahua puppy, understanding their physical development, especially when their ears tend to stand, can be very helpful.

At What Age Do Chihuahua Ears Usually Begin to Stand?

Chihuahua puppies typically enter the world with folded or floppy ears. Their ears often start to stand on their own between 5 and 15 weeks old. This timeline can differ for each pup, influenced by factors like genetics and coat type. For example, long-haired Chihuahuas in the US tend to have ears that take a bit longer to stand upright compared to their short-haired counterparts.

General timeline of ear development:

• Birth to 3 weeks: Ears are floppy as puppies are just beginning to open their eyes and ears.
• 5 to 12 weeks: Many pups begin to show ears partially or fully standing, commonly between 8 and 12 weeks.
• 4 to 6 months (Teething period): During teething, some pups’ ears may droop again temporarily due to changes in muscle tension.
• After 6 months: Most Chihuahua ears will have taken their adult position; if floppy, chances are they will remain that way.

How Teething Influences Your Chihuahua’s Ear Position

Between 4 and 6 months, Chihuahua puppies undergo teething as their adult teeth replace baby teeth. The vigorous chewing activity often weakens the ear muscles temporarily because these muscles connect with jaw muscles, leading to ears that may droop once more.

This change is quite common and may affect either one or both ears, sometimes fluctuating daily. Thankfully, once teething concludes and the adult teeth are in place, the ears usually regain their firmness and upright stance.

Will My Chihuahua’s Ears Remain Standing Permanently?

By the time your Chihuahua reaches around 8 to 9 months, if their ears are still floppy and have not stood up, it is likely that they will remain soft. While upright ears are often preferred in dog shows and by breeders, floppy ears pose no harm to your pet's hearing or overall health.

Chihuahuas with floppy ears often retain an endearing, youthful charm. However, floppy ears may increase the risk of ear infections or mites, so consistent ear care is crucial.

Top Care Tips for Floppy or Folded Chihuahua Ears

• Routine cleaning: Use a veterinarian-recommended ear cleaner to carefully remove wax and debris, but don’t over-clean as it might cause irritation.
• Keep the ears dry: After baths or swimming (popular for some Chihuahuas in warmer American states like California and Florida), dry their ears thoroughly to prevent moisture buildup that can cause infections.
• Regular checks: Inspect your pup’s ears frequently for signs of redness, inflammation, unpleasant smells, or discharge, all potential indicators of infection.
• Consult your veterinarian: If you notice warning signs or discomfort, promptly seek professional advice to safeguard your dog’s ear health.

Summary

Typically, Chihuahua puppies’ ears begin to stand between 5 and 15 weeks, though they may droop again during the teething phase between 4 and 6 months. By about six months, you can usually tell if their ears will be permanently erect or floppy. Maintaining proper ear hygiene is essential, especially for floppy ears, to help prevent infections and keep your little companion happy and healthy.
