I regret getting a puppy and I don't know what to do.

I am sorry you feel this way about having the puppy. Previously, I have always had rescue dogs, which were already house trained and calmer. However last year we got our first puppy, I honestly did not understand the amount of work it would take. I have heard alot of people say having a puppy is like having a new born child and I completely agree with this. It is so disheartening to come home to your house covered in wee and things that have been destroyed. My puppy teethed for a long time and for some reason he would chew and bite on my hands, he would only listen to my partner and my partner would often come home to find me in tears. Therefore I would not enter into this decision lightly as it is time consuming and hard work. I love my dog and although it was hard work, I wouldn't change him for anything, he is toilet trained, independant and very loving, and it is very easy to forget all the stress that was caused. I think you need to speak to your boyfriend and ask him if he knows what he is getting himself into, does he have enough time to devte to the dog and does he know the impact it will have on your relationship.
