My little collie has a history of being difficult to "catch". He used to do that infuriating thing where they say just out of reach. I tried everything (and it's bloody difficult being cheerful and happy on the beach, in the dark, in winter when he's been ar*ing around for over an hour) but we got there in the end. Or so I thought! Today I just could not get him to come at the end of our walk. I don't know if it has anything to do with him getting a bit of a doing from a wee terrier earlier (no actual harm done, just lots of noise) and him not being out for a proper walk all week (I've been a bit poorly). It's very disheartening. I was wondering if anyone had any thoughts about how I should manage this. I can always tell when he isn't going to come by his body language (though I have difficulty describing it) and, as I said, it hasn't happened for ages. In the past I have tried all the usual stuff (he was on a long line for about a year at one point) and somehow the behaviour just faded away. Am I overreacting? Should I just treat this as a blip and not change anything? Today I was worried that he would start to chase some children who were playing on scooters (he's a bit fixated with wheels--though he doesn't chase bikes or prams. He chases our wheely bin and the weelbarrow, which isn't a problem. Well it hasn't been.). He's also terrified of skateboards-I think it's the noise- and I've been trying to get a hold of one so I can leave it, unmoving, in the garden and gradually get him used to it. He would bark furiously at them and I think it would be a bit scarey for kids. I was a bit concerned today when he was running around refusing to be caught that a kid on a skaetboard would appear and he'd go a wee bit mental I think he sensed my anxiety. Phew! Sorry to be so longwinded. All suggestions gratefully recieved. Thank you.
