1, a dog gets up early, which means its biological clock is normal. Look for mom after waking up (now she has left the kennel and the owner is mom). If he can't find it, he will be anxious and scream, which is normal. You can let him scream and get used to it for a while, or you can let him go to bed and hug the water, so that he won't scream badly when he wakes up-but this is not recommended, and you can't always hold him to sleep. Never wear a mask or anything.
It's only been two months. It is difficult for you to make him poop correctly in any way, but stick to your correct guidance method. Generally, dogs will gradually develop habits after three or four months, but there will be differences between individuals. Keeping a dog requires patience and hardship. There is no way.
Feed proper dog food, and now eat at least three meals a day for two months. As for when he will solve it, just let him, no one will fix it! A friend said to take the dog out for a walk, and I am very opposed to it. Dogs are too small and have poor immunity. I saved it for about four months before I took it out, so the risk was low. Of course, you can take it out. Try to walk in a clean and flat place. Other dogs walk less.
4, the problem of biting people, now it is not biting people, but grinding their teeth. It is normal for him to grow teeth, change teeth, itch and bite things. Buying toys like chewing gum can play a certain role. As for him who is not convinced of you, he must be in charge. Samak's training level is not very high, but he must obey.
