Thank you for you advice, it is appreciated.

Hello,

I have two 11 year old males. Both were neutered as pups. Over the past year and a half they have definitely exhibited signs of aging. Not being able to walk as long as they used to, etc. However over the past month one has started to becoming increasingly aggressive towards me when it is time to go in his kennel, etc. and is only willing to walk about one block?

Has anyone experienced a Basenji becoming aggressive as they have gotten older?

Wondering if it means that time is near, but I can't have him behaving that way.

Thanks.
