Jealousy in dogs usually occurs when several animals live in a household, between which the ranking is not clear. Especially dominant breeds are more prone to jealousy, as are dogs from the same litter.
Jealousy in dogs is a tiresome topic for the masters of ticks. However, it is often caused or at least intensified by people's behavior. This happens mostly unconsciously:
Jealousy in dogs - on what?
The owner's attention, food, toys or sleeping place: these are all things two or more dogs living together need to agree on. Those who gain the upper hand in case of doubt clarify the animals only by themselves, in which they determine the ranking.
A master, who tries to settle quarrels, interferes with words or gestures, consoles, defends or praises one of the two animals, aggravates the difficulties between the two and can make sure that jealousy arises. So remember, dogs are pack animals and one is always the boss!
What master means well and can take dogs wrong
Once the hierarchy between dogs has been clarified, small conflicts usually resolve quickly. It becomes problematic when the master ensures that it is always fought over again. This can be caused by very simple misunderstandings in the communication between humans and animals.
A case study: They stroke the lower-ranking dog and suddenly the higher rank decides that he is now off. He intervenes and drives out the other. Even if the lower-ranked one is so sorry for you, leave it at that. Now if you scold the one dog and console the other, the lower ranked one will have to feel it later and fight the fight again, which he'll lose anyway.
This does not mean, of course, that you should keep completely out: you are responsible for an equal treatment of the dogs, a good dog training, appropriate welfare and for separating the two in an overly violent quarrel as far as possible without singing and soundless for a short time, until the mind has calmed down.
