How should I introduce a new Great Dane to my existing dogs?

Introducing a Great Dane to your existing dogs involves many of the same foundational steps as any other breed, but their massive size, clumsiness, and unique play styles require some specific considerations. Great Danes are affectionately known as “gentle giants” and are often goofy or even afraid of harmless things like frogs or ceiling fans. However, because they don’t always know their own size, it is important to manage their environment carefully.

Here is how you should handle the introduction and integration of a new Great Dane:

The Initial Meeting

• Use neutral territory: Always introduce your new Great Dane to your existing dogs on neutral territory rather than in your home or yard.

• Take a walk together: The best approach is to walk the dogs together at a distance. As you walk, gradually decrease the distance between them. This allows them to greet each other calmly rather than in an overly excited state.

Managing the Home

• Respect the “honeymoon phase”: It typically takes two weeks to a month for a new Dane’s “honeymoon phase” to wear off. Be patient, as it will take time for the new dog to fully settle in and show their true personality.

• Separate feeding and sleeping areas: If you use crates, keep their crates separate. You should also feed them at the same time, but keep their bowls several feet apart to prevent them from feeling competitive over food.

• Supervise high-value items: Hidden triggers can spark sudden, intense fights. You must highly supervise the dogs around new, high-value items like stuffed bones, as even normally friendly Danes can instantly become aggressive if another dog tries to take their treat. (Old bones are usually less of an issue.

Understanding Great Dane Play

• Expect rough and loud wrestling: Great Danes play very hard. When they wrestle and collide, it can sound incredibly intense—like the scene in Rocky where he punches the meat. They may show their teeth, joust, and use fake growls, but this is usually just harmless fun.

• Monitor for clumsiness: Make sure they have a safe space for their daily zoomies and roughhousing, as they can run into each other (and your furniture) quite hard.

• Be patient with rescues: If you are adopting a rescued Dane, be aware that they might not understand how to play with toys or other dogs right away, and may initially just want to chew bones and receive constant affection.

A Note on Gender While Great Danes generally get along wonderfully with other dogs, some owners note that having two male dogs or two female dogs can sometimes open the door for same-sex aggression. If your current dog is a male, you may have an easier time introducing a female Great Dane to the household.
