Thank you. That was really useful advice. (I know it wasn't for me but it saved me asking a similar question! ) Today, I started the lead with Oscar as he's going for his first walk on Friday. We started with the collar a few days ago for short periods at a time. I let him trail the lead around the garden and then held it for a short while. He was biting the lead a lot, should I discourage it? I got a harness from the pet shop but is it ok to attach the lead to the collar? (I actually purchased the lead and collar together but got a harness as well). I was advised to use a harness but I feel it's too much for Oscar. Is there anything I should know about attaching the lead to the collar? Is there a particular way that is dangerous? Obviously I realise what movements would choke him but I'm worried I'll pull too hard as I know it will be challenging going for walks when he's first getting used to the lead.
