You know a dog hates another dog through aggressive body language like a stiff body, raised hackles (fur on the back), tense tail, intense staring, growling, snarling, snapping, lunging, and baring teeth, often accompanied by avoidance signals like lip licking or yawning, indicating fear, stress, or territoriality, says, K9 Basics, RSPCA. These signs signal a dog feels threatened or uncomfortable, demanding intervention to prevent escalation, according to, Petbarn, Dogs for Good, K9 Basics.
But here are some things to watch out for: Staring, stiffness, tail wagging high up, twitchy body movements, quickly approaching another dog head on, lifting her head above the other dog's or onto the other dog's shoulders, hair standing up, excessive/persistent mounting, and of course growling, lunging, etc.
Don't worry about them, though: focus on controlling the things you can control: reassure your dog that all is fine, avoid confronting the other dog if at all possible, and if not then only do so while remaining calm and in control. Then, just walk him away from the situation, and everything should be absolutely fine.
"Red Flags":
This is especially problematic if it is associated with growling, stiffening of body postures, or a snarling display of teeth. These behaviors indicate fear or pain and should be evaluated to make sure there is not a major underlying problem.
While it seems dogs do forgive after a fight, there's still a lot more to learn about reconciliation in dogs. In some multi-dog households, it doesn't always work out. Shyan-Norwalt has observed dogs in the same family who did not reconcile but instead separated after every conflict.
Signs can include growling, baring teeth, snapping, and biting. These behaviors could stem from fear, territorial instincts, protection, or past trauma. Ignoring aggression can lead to dangerous situations for both your dog and others.
Dogs generally decide whether they are compatible with another dog in approximately 3 seconds, so if your dog's body language is indicating they are comfortable to go in for a greeting and the body language of the other dog also looks good, check with the owner of the other dog and if permission is given, let them go ...

The seven second rule. Put the back of your hand on the pavement. If you cannot hold it for seven seconds, it is too hot to walk for your dogs. This rule also applies to dogs riding in the bed of a pickup truck.

Cobbing is a common term used to describe a dog using its front incisors to nibble, much like the way corn is eaten off a cob, hence the name. This behavior is generally harmless and often a form of communication or expression.
Dilated cardiomyopathy and many congenital heart diseases are also commonly found in the Great Dane, leading to its nickname: the heartbreak breed, in conjunction with its shorter lifespan.
Signs Your Dog is Stressed and How to Relieve It
Stiff Body and Tail: A dog who's feeling aggressive isn't going to be all wiggly and relaxed. Instead, they might stand super straight with a tail raised high or tucked down low. Baring Teeth: A dog showing their teeth and growls says, “Back off!” Intense Staring: Dogs use their eyes to communicate a lot.
Aggression
Maybe. But not always, and definitely not right away. We've seen dogs successfully re-integrate after serious fights, but only when the situation is handled with structure, safety, and the right training approach. In some cases, peaceful co-living isn't realistic or fair to one or both dogs, and that's okay, too.
