My working cocker is 12 months old. She has taken well to training and has excellent recall. I walk her twice a day, usually in the woods near my house. She absolutely loves pottering around and sniffing in the woods.
I don't ever take a ball out for her because when the entire household had Covid in the Autumn we exercised her by throwing a ball for her in the garden. She became absolutely obsessed by it, and didn't want to do anything else. Obviously it's not great for her joints, and it seemed to send her quite manic (usually as long as she has her walks, she is really chilled in the house).
The problem is when other owners walk through the woods with a ball thrower and ball. She immediately sits next to them and wants to have a game. Lots are really good and stop throwing the ball for their dog, get mine back on the lead, and take her away, but others just merrily continue throwing balls about and wondering why my dog suddenly won't leave their side.
I take high value treats out with me, and she does come back to me, but to her a ball is really the highest value treat. Do I need to start taking a ball out with me to distract her if others have balls? It just makes me a bit sad because if there's a ball about she won't sniff or explore at all, she just stares single-mindedly at the ball, and it just doesn't strike me as being entirely healthy for her!
