@Sparkle79 we have been doing 2 short lead walks every day and every time he pulls we just stop until he gives some slack on the lead then we say 'let's go', it was sometimes every 10 seconds. Literally just that over and over again. When he realised we weren't moving anywhere he tended to look back at me which showed he was giving me his attention then we could move on.
He has a habit of getting under our feet as hes often trying to see where I am so we also praise with a 'good in front' when he's walking nicely in front of us.
Heel is proving a bit trickier as we were trying the treat down by our thigh but because he is so small he was constantly jumping up to get the treat so we are now trying just tapping our legs so he comes closer then if he stays for a few steps we treat then. We are trying to use heel to get him to focus on us when there are other people/dogs/scooters passing us. He is better on the pavements with this but in the park is way more excited.
@Plantlover23 how exciting re day care, I have booked some sessions with the trainer for her to take pugpup out for solo walks. Will be good for her to do some work with him on her own and also it will be so nice to have half hour alone haha.
