When our lab was younger she was stubborn on walks. If we chose to walk a way she didn’t wish to go she would arch her back, put her head down and look at you to say ‘no chance, I’m not going that way’. She wouldn’t move until you went the way she wanted or coaxed her with a treat/distraction. This stopped and she was walking lovely for months. She’s now turned 19 months and she seems to have changed personality over the last 5 weeks (since her last season). She’s become more sleepy, lethargic and quite clingy to me (previously there were no evening snuggles for me but she now happily lies with me). She has also started this odd walking behaviour again. A walk we’ve done most mornings has now become a walk where she refuses to go the way I want and puts her head down to say ‘not that way’. Shes also started doing it with her walker at lunch. Evenings aren’t so bad as we tend to go a different route and for longer. I’m quite concerned about her chance in behaviour as she looks quite sullen - perhaps like a grumpy teenager - anyone have any thoughts on this? Is it perhaps an age thing?
