Are Great Danes Good With Cats? [With Tips To Help Them Get Along]

Great Danes’ cheerful, easy-going personality wins them lots of friends. They are a great family dog and friendly with kids. But are Great Danes friendly with cats? I decided to research and discuss the subject with pet owners who raise Great Danes and cats under the same roof. I’d like to share my findings with you here today.

So, are Great Danes good with cats? Great Danes can get along very well with cats. Great Danes are usually friendly with all animals, including cats, if they’ve been properly socialized. However, Great Danes that haven’t been around cats early in their life may mistake a cat for a prey animal. It can result in chasing, catching, and even an attack.

If you have an older Great Dane and want to get a cat, you will need to spend time helping your dog adjust to them.

It may take a few weeks, but over time the two should get along very well together.

The truth is, the answer to the question if Great Danes are good with cats is yes and a no, it really depends on how the Great Dane has been trained.

Its all about getting the two animals used to one another and helping them to perceive one another as a ‘friend’ and not a threat.

Let us now take a closer look at how these animals generally respond to one another along with some practical tips that you can use to help foster a relationship between them.

Do Great Danes Get Along With Cats

Great Danes should get along with cats so long as you have established a safe environment and relationship for them to be able to do so.

If you would like your Great Dane to get along with your cat, you’ll need to ensure that both animals have been properly socialized.

The best chance of success, and that will make it a much easier process for you as an owner, it to ensure your Great Dane has learned from a young age that a cat is not a threat, toy, nor potential prey.

Interestingly, cats tend to keep themselves to themselves so they are usually not the one to worry about!

Socialization means your Great Dane has been exposed to all kinds of people and animals, including cats as a puppy. It also means exposing the pup to loud sounds, new places, different people, and different experiences.

This all ensures your dog perceives their environment in a friendly and inquisitive way.

Socialization tips for your Great Dane pup to get used to cats and other dogs:

  • Take your puppy on lots of walks to acquaint him with noises, smells, and other animals
  • Allow your Great Dane pup to sniff and see new animals – rabbits, cats, or even horses.
  • Stay calm and talk softly to your dog as they sniff the new animal. Keep them on their leash, never allow them to chase the animal.
  • The best age to begin socialization is anywhere from three to twelve weeks.
  • After your pup has reached four months, it gets harder to socialize them.
  • Another option is to enroll your puppy in an obedience class where they make sure your pooch is exposed to various people and situations.

All these things together teach the puppy to be well rounded and flexible when it comes to change.

So that when they’re older, if they’re in a new situation or encountering a new animal, like a cat, they won’t freak out about it.

Full-Grown Great Danes Can Learn To Like Cats

If you have an adult Great Dane and you’re bringing home a new kitten, you may not know at first how your dog will react.

Your Great Dane may love the new kitty and adopt it as their own, or they will thing the cat is a threat to his turf.

Some of it depends upon your Great Dane’s upbringing and some of it depends upon your Great Dane’s personality.
