puppy not learning

Rocko is 14 weeks now and he isn't getting better with strangers or new dogs. He bites really hard with strangers and gas ripped down my neighbours hand. I make him sit when new people approach to stroke him but as they get closer he us jumping of the floor trying to get them. With dogs we meet on his walks he just wants to jump on them and bite there neck. I feel embarrassed as I think the other dogs owners think "he doesn't train him" im trying my best and he is in puppy classes but it's just really hard. Could anybody advise what I should try?

just keep up with all your training some just take a bit longer than others,great he is going to puppy classes,they will really help

Lots of treats and praise when he does do what you want

Patience really is the key the dog classes will be helping massively.

14 weeks is still really young and he's still learning. Stay consistent and you will see a difference, it just takes time. Hang in there, they will push your patience but it's so worth it

Baxter is just six months and we are starting to see a difference, hang in there it will get better

Hang in there it just takes time Bane is an angel in the house but on the streets he's like a terror! He is a year old now and still will take a leap to someones face for a lick if we don't keep hawk eyes on him!
