We have two Blue Heelers that are 4 months old. All progressing very well with games etc until I connected them to the leash for the first time. The first time I just let them run around with the leash connected to their collar for about 30 minutes watching them to make sure they didn't get hung up on any obstacles. Went fine, they ran and played with only a slight concern that this strange cord followed them. However, today trying to use it for recall they just had a fit. Jumping and pulling and just nuts so I took off the leash and searched for any advice here on how to go forward. Probably here but wasn't able to find any information. Can you direct me to the info or give advice here in the forum.
Thank you!
