Our puppy (a male, intact husky x lab) is now 20 weeks old. A fortnight ago I was confident that we had nailed recall: it had been 3 weeks since it last failed and he passed what I thought was the ultimate test - coming back on a whistle after chasing a deer. He still pulled on the lead sometimes and ‘drop it’ and ‘leave it’ were inconsistent, but we seemed to be making steady progress. In the last week he has regressed almost completely. He will only respond to commands if there is a tasty treat on offer. One thing occurred to me - could the difficult ‘teenage’ period be starting early? We have started to see some new behaviours recently. He is humping cushions much more, now with his “lipstick out”. He is not cocking his leg to pee yet but now does several little pees on his walks instead of one long pee.
