She's 16 and a little terrier mixture and the light of our lives but I think the time might be approaching. She's been increasingly deaf and has severe cataracts in both eyes, now seems bewildered a lot of the time and is leaving small puddles where she's been sleeping (she still goes outside frequently to toilet too)
She's following me around more and more, barking at nothing especially in the evenings (was never a barky dog) and routinely goes to bed about 11pm and stays there til lunchtime now 
I need to have another chat to the vet don't I, there's no acute medical problem it's just been steadily downhill over the last 6-9m
