Our 11 month old puppy is trying my patience somewhat...
He is, 95% of the time, a happy, fun and affectionate pup. However, over the last few weeks he has started to growl/snap at us. It's mainly, but not exclusively at DC (age 9), although there has been a distinct improvement with this. DC is being firmer and calmer with him, and perhaps a little less of a playmate, and he seems to be responding to that. DC is also getting more involved with the training too.
It happens rarely with me, which may be as I am chief walker and feeder etc.
I'd say it happens more often after a walk, so when he is already excited - perhaps too excited. There are also some days when he seems very susceptible to outside noise eg the bin men arriving etc. Although I'd say this too is much better than it was.
This afternoon he reacted with lots of barking when DC came through a particular door, and he wasn't expecting it. (He had a particularly lively walk today, and had a zoomie when we got home, so perhaps was still calming down from that).
I am hoping this is just adolescence, and hormones, and it will pass... Sometimes this feels more challenging than having a baby! I'd be grateful for more experienced views though.
I grew up with dogs and don't remember this phase, possibly as I wasn't the one responsible for them, and of course each dog is different.
