Rory is nearly 8 and I'm having to have him castrated due to medical reasons. Has anyone noticed changes in an older dog they've had castrated? Mentally or physically?
Firstly, I hope Rory's OK, recovers well and any underlying problems can be 'sorted'.

We had a springer castrated at 6 and it caused no mental or behavioural changes at all. Physically, he weighed a bit less at the back end :wink:
I did wonder about muscle wastage? Changes
