Hi all, im new to this forum and just have a quick query I hope somebody can help me with I have a border collie puppy who is 4 months old, he's a lovely little chap and we are having no problems with him - ive had border collies before over the years but they have always been rescue dogs - therefore not puppies so this is my first collie puppy My query is this - when we go for walks he is generally excellent, walks to heel, sits and waits at kerbs etc. but he has a "thing" about grass, gets very excited if we are near grass or if he gets a paw on it - i dont let him go on the grass until I decide however the last few days he has started to literally "take off" when he sees/smells grass. I instantly stop - dont pull him back just stop so he tends to almost spin on the lead, he'll then run back to me and jump up biting and snapping at my legs and biting the lead. I know this isnt an aggression issue, he is just very overexcited - its cute and almost comical in a puppy of his age however I do NOT want it to escalate so he's doing it when hes a 40 pound adult and it wont be so cute then! Any ideas of what I can do when he does this will be greatly appreciated. Sorry I went on so long!
