You so know the breed when you said sensitive, they are so fickle! Mines just taken all day to eat his bonio, me and oh laughed, it's a collie thing!I’ve only ever had pups, the last one was a risk and sadly it didn’t pay off. I love collies and if I get another it will be a pup but I’m so torn as I know they can be quirky and sensitive even if you get them at 8 weeks and put time into training and socialisation. I definitely need to give it some more thought before making a decision
Good on you for really thinking about it, when I got the one I have now, the owner would only only let the pups go to folks who have had experience with collies.
