Troy's getting older

I will need to take Troy back to see Mark at some point (need to get Dylan sorted out first). He is starting to have cognitive problems I think, sometimes he won't respond when I call him, he sometimes stares into space or at a certain area, and he also poos indoors at times. It isn't very often yet, but more frequently lately.
Last night, I let him out at 5 am because he asked. He went for a wee, then came back in, and pood in the sitting room! Luckily it is dry and well formed, so easy to clean up and not a problem, but Troy doesn't like it; he was always so clean! I think he just forgot what to do outside, or wasn't quick enough to go back out... I think that's the problem really. He can't hold it very well anymore and by the time I get to him (or when I am not at home), it is sometimes too late.

I have just bought some Aktivait, many people report that this really helped their old dog. I'll see how we'll get on... If it makes no difference, then we are probably looking at Vivitonin from the vet's.

I hate seeing him getting old, but I guess it catches up with us all.
