Stress in dogs works in a similar way to humans. Dogs also become stressed in situations that they cannot cope with, such as: pain, threats, excitement, etc. This can be expressed in different ways in dogs. If the stress comes from the environment, dogs will send out calming signals. The better an owner understands these signals, the quicker he can intervene to change the situation so that the dog's stress decreases. When the calming signals have no effect because the owner does not understand them, a dog will use distance increasing signals. (flee, do nothing or defend).
When a dog has been in a severe stress situation, it takes a number of days before its adrenaline level is back to a neutral level. This means that dogs that are exposed to this type of situation every day, for example by continuously fighting on the lead, being left alone every day due to separation anxiety, being forced to learn something, having to live with an Anti-Bark Collar, constantly have an increased adrenaline level with all its consequences. Prolonged stress in dogs is pure poison for the dog's body. Dogs then run the risk of physical problems, such as allergies with itching, stomach and intestinal problems, heart problems, etc. So try to avoid stress as much as possible, and otherwise try to remedy it with calming supplements or herbs.
