Hi all. Just after a bit of advice. Whenever we go out walking people rush over to see my 16 wk old pup. They all make a fuss and he jumps up and loves the attention. This is fine now he's little but I don't want him doing it when he's bigger. I try to get him to sit but people don't give him the chance (not that he will listen as he's so excited). What's the best thing to do? He loves meeting new people so I don't want to stop him meeting people but just don't know what to do.
