Dogs do not usually recognize themselves in the mirror as most dogs tend to bark at themselves in the mirror thinking the dog is another dog.
My own dog will bark at himself every time he gets in front of a mirror so he thinks the dog he sees is another dog like him and is confused.
Dogs can and do cry and the dog sometimes sheds tears when they cry as well.
Most often dogs cry by whimpering, whining, howling and mewling.
Dogs can't answer yes or no nor can the dog learn to understand yes and no.
However you can teach your dog to respond with yes and no movements to your covert hand gesture, but the dog will never understand the concept behind the words yes and no.
Pulling a dog's scruff does hurt so you should not pick up a dog or pull them by their scruff as pulling the dog's scruff is painful for them.
All dogs have scruffs (the loose skin located around their neck.)
The dog's scruff has a very distinct purpose from early on.
When you look at the way mother dogs interact with their pups, you will also see that they often pick the pups up by their scruff.
They do so to carry them from one place to another.
It's not cruel to crate a dog during the night or while you're away from home.
Crating the dog keeps the dog safe during the night or when you cannot be around to supervise them and prevents them from getting into things or tearing things up during the night.
Crating the dog during the night is a good thing unless the dog wants to sleep with you and is good about staying in the bed with you.
You should not leave water in the puppy crate at night as they will usually need to pee afterwards.
Simply allow the puppy to have some water before they go to bed at night and they should be just fine through the night without needing to drink any water.
Puppies should always nap in their crate as the more often the puppy uses their crate the more used to the crate they will be.
The puppy should also sleep in the crate at night so they don't wander around the house at night.
You should encourage your puppy to nap and sleep in a safe place: a crate, a dog bed, or a quiet place in the house where they can nap undisturbed.
It may take time for the puppy to get the idea, but eventually they will recognize that spot as the place for sleep.
You cannot really spoil a puppy by holding it too much.
However you should not hold a puppy too much as it can cause health issues with the puppy and may cause the puppy to develop weak muscles as they need to walk and move around to strengthen their muscles.
It's normal for puppies to want to be held all the time.
They are a lot like babies in the first few weeks and can drive you crazy with their insistent crying and clinginess.
What you have to do is be patient, keep the puppy close until they adjust, and provide enough physical stimulation.
Affection is an important part of the human dog bond and when thoughtfully utilized, can be beneficial for both dog and owner.
However badly timed affection can worsen problems, build over stimulation, reward inappropriate behavior, and create instability in some dogs.
Only holding the puppy for one or two minutes at a time is ideal.
As time goes on and the puppy become less dependent on their mother, you can hold them for longer.
Never take a puppy off his mother while he's breastfeeding, because drinking her milk is crucial for his health and natural development.
If the puppy continues to cry for a long time, then there may well be something you need to help them with.
If you do go and check, limit your time with them.
Check if they need the toilet or if they are hurt, then settle your puppy again and leave.
If they start up again, as hard as it may seem, leave them alone.
In general, the minimum amount of interaction time for a puppy to be happy and healthy is two to three hours per day.
This will give you enough time for training, play, cuddling, and feeding.
Small dogs or puppies that demand to be picked up or put down should not get what they want until they sit or do another acceptable quiet behavior.
They should not be put down unless they are settled quietly in your arms.
