No, It's very normal, although I do not know why they do it.
so they want to warn their enemy or they want to be safe
No, if it is cold (or any temperature) the dog should not sleep wet. I will get sick... ARE YOU TRYING TO KILL YOUR DOG??!!
It is not good for a dog to seizure, foam in the mouth, and flinch from human touch. It may mean that the dog has rabies. It means you may have to shoot the dog.
The dog is uncomfortable around humans still, maybe. Most dogs are like that.
bring the dog to a vet immediatly!
It is typically not recommended for your dog to sleep with you while they have worms. This is because worms can be passed between humans and animals, increasing the risk of transmission. It is best to keep your dog in a separate sleeping area until they have been treated and are no longer contagious.
trying to make your dog evolve! man's bad enough!
My dog has a doghouse that she will sleep in but it used to belong to our other dog.
A dog trying to stay awake may exhibit behaviors such as restlessness, frequent blinking, yawning, and difficulty keeping their eyes open. They may also pace around, fidget, or have trouble settling down to sleep.
To get your dog to sleep with you, create a comfortable sleeping space for them near your bed, establish a bedtime routine, and provide positive reinforcement when they sleep in the designated area. Consistency and patience are key in training your dog to sleep with you.
This will sometimes happen if the dog is scared of you. The dog is trying to show submission to you. Try to not yell to much and scare the dog, just be firm and clearly show what behavior it is being punished for.
A dog may sleep in a number of ways depending on what makes it comfortable. It may sleep on its side, flat on its tummy, or coiled.
