The bond of a pet and owner mostly stands on the foundation of trust. 

U might trust your litle loyal friend for u have chosen it to be your companion but earning a dog's trust and affection is a tough task it isn't as simple as a bunch of treats or a few love caresses. But once the dog trust u it shows it in different ways. 

Dogs sometimes require years together to trust any human this mostly happens with rescue dogs as they have been prone to many injustices thought their past it hence takes them time to realize that their present companion won't hurt them. 

A few dogs take months to trust a human completely, this occurs when the dog u got have exceeded the age of 2-3months and differs from breed to breed though some people prefer a dog which is older and trained but for them it might be difficult to earn it's trust specially when u plan to discipline a dog with Hitler means and punishments 

Dogs are quite similar to Humans in case of emotional balance they have various emotions in them from love to resentment the dog loves u or resents u completely depends on the way u treat it.. 

A few lil pups take only a few days to completely trust a human this happens when a just born pup or pups aging from 1day to 5day are got. 

In some cases the topic of trust doesn't arive as people get the pup the moment it is born.... Yeah they do and this is heartless but it also has some sideffects on your lil companion though u think that since the moment it's is born getting it would help u forge a child parent bond but it hinders the development of your pup and and slows down its immune system. Making it weaker in comparison to other dogs of his breed. A new born pup shall spend atleast 28day with the female dog which had given birth to it after that u can take that dog. In these 28 the mother dog  nourishes her pup with mother milk which is regarded as important in humans also and dogs aren't any different this mom's milk helps the dog stay healthy and increases their life span if u want your friend , your child to live a lil bit longer then have some more patience like u had till it's birth and let it stay with the mother dog.

The dog's trust is also linked  with it's health, if your dog doesn't trust u it won't prefer being around u and will feel scared and depressed causing mental ailment to your companion so make sure u can make your lil dog trust u if not let someone it trust around it all the time telling it about your goodness so that it trust u 

HOW TO MAKE THE DOG TRUST U????????? 

This is an Important question, the only way your dog trusts u is when u show some strict love to it like 

If your dog commits a mistake 

Then instead of shouting at them say in a polite manner 

"snoopy is a good boy right my lil good baby won't do this right this is bad thing mumma 's good boy won't do this" 

(in place of snoopy take your dogs name, and if it's a female  say good girl, if u are male member say dad) 

If your dog does something good and u wanna praise them instead of giving them a bone 

Say 

"snoopy good boy mumma' s boy is Very good he did such a good thing he is the best mumma is proud of u" 

(instructions same as the above one)
