Or any dog that is no longer in the puppy stage!
We recently rescued a 5 year old dog. I love her. She's bloody wonderful and already I can't remember how I coped in a house with just one dog for company before she came!
She came to us with supposedly excellent recall, and after about the first week of settling her in, she did seem to respond really well to being called. I also introduced the whistle (so she had the same recall signal as our other dog) and she picked it up amazingly quick.
Only, I think I've gone wrong somewhere because she now only comes to the whistle 50% of the time. I'm not sure if she's just getting more confident in our surroundings now, or if I need to start training again.
I've found her 'holy grail' of rewards (a squeaky ball) but even today after not having the ball all week (after losing it in the sea!) she just wasn't interested and wanted to sniff out everything else on our walk.
I've noticed her getting bored too (she's a cocker) so have started making meal times into a game to keep her mind busy. She gets tonnes of physical exercise, but I think she needs mental stimulation just as much. I'm also wondering if that's why she's not responding to recall - because she's bored/frustrated?
Anyway, it's clear I need to think up some other kinds of games to do with her during the day, and try again with the recall, but is it possible to ever get to the point of trusting recall to the point of letting her off lead where we are likely to meet other dogs?
