When Do Australian Cattle Dogs’ Ears Stand Up? A Guide to ACD Ear Development

As a proud owner or potential adopter of an Australian Cattle Dog (ACD), you might be wondering when your pup’s ears will stand up. This is a common question among ACD enthusiasts, and for good reason – these dogs have adorable floppy ears that eventually perk up as they mature. In this guide, we’ll explore the development of ACD ears and when you can expect them to stand up.

Australian Cattle Dogs Ears Development

Like many breeds, ACD puppies are born with floppy ears that gradually begin to stiffen and stand up as they grow. This process is due to the development of cartilage in the ear, which provides support and structure. However, the timeline for when ACD ears stand up can vary depending on a few factors, including genetics and nutrition.

On average, ACD ears will begin to stand up between the ages of 3 to 4 months. However, it’s not uncommon for some ACDs to take longer – up to 6 months – before their ears fully perk up. This is largely due to genetic factors, as some ACDs have more or less cartilage in their ears than others.

Tips for Promoting Ear Development in ACDs

While genetics plays a large role in when ACD ears stand up, there are a few things you can do as an owner to help support healthy ear development:

  1. Proper nutrition: Providing your ACD with a balanced, high-quality diet that includes adequate protein and nutrients can help support the development of cartilage in the ears.
  2. Good posture: Encouraging your ACD to stand up straight and avoid slouching or folding their ears can help promote proper ear development.
  3. Massage: Gently massaging your ACD’s ears can help promote blood flow and support cartilage development.
