Domination!!!
When a dog puts his chin on another dog's neck, it is a sign of dominance or control. It is a way for the dog to assert its authority over the other dog.
Please give more detail to your question. What do you mean by when a dog fights over mate. However a dog will fight over another dog until one dog is hurt or the mate chooses.
If the other dog was off leash, then probably not.
You just keep telling the dog over and over it then will remember the command.
It could be from playing with each other and they are just tired.
yes
From over miles. AKA. 1+miles
Just wash your dog with Johnston's baby shampoo or other dog shampoo and rinse very well.
MY 1 YEAR DOG SPRAY ALL OVER THE HOUSE IS IT BECAUSE WE HAVE ANOTHER MALE DOG
You just had a bad dream.
Yes. If one dog feels another is getting more attention, food, play time or just because that dog has to share its owner with another, it can get jealous. Just like humans if your friend starts to get close to another person some people can get very jealous and spiteful. Its much for muchness. For any mammal.
When a dog bites another dog's back legs, it could be a sign of aggression or dominance. It may also be a way for the biting dog to establish control or show its superiority over the other dog.
