I am very sorry that this is been a difficult experience so far having a puppy. perhaps the stress your feeling is what the puppy is picking up ... AS what was mentioned in a previous post , puppies and do pick up on their owners emotions and feelings towards them. They are especially prone to any kind of negaitivty or rough handeling or treatment. Not saying that this is what has happened . Just mentioning it because puppies are very sensitve to changes, noise or any type of sudden movements , which may or could have scared him, without even knowing it.
I am tying to say this in a thoughtful manner without being hurtful. And to be supportive, not unkind.
Maybe, offereing treats, and trying to play with him one on one on the floor letting him come to you. Remain still , allow him to come to you. Let him jump in your lap if he wants to. Offer him toys and squeak them try to engage him in play. See if he will let you play with him on his own terms. Puppies love to play, and usually can't resisit a good playtime with someone willing to play on netural terms. Try not to make eye contact. This can be a threat to any dog. Talk to him in a high pitch voice, a puppy loves it. Spend lot's pf time playing with him, then petting him softly. See if he rolls on his back for a belly rub. If he does this is a great sign. My Suzi loves to be petted right behind her ears. most pups have certain petting spots they just love to be petted the most. Your puppy will come around. Try not to take his rejection personally. He needs time to warm up to you. He will. Try some of these methods and perhaps more YTer's will have ideas that can help you as well.
Best wishes to you.
