Hello, I'm new here, and could really do with some help
My little dog (poodle x bichon, that I've had since a pup) is now 14 1/2 and over the last couple of years has lost her hearing and her vision is starting to go as well, but other than that she's fit and well. She doesn't run quite as fast nor jump quite as high but fantastic for her age...always supprises people how old she is.
The problem is that since she's gone deaf, her sense of smell is soooooo important to her, that walking her has become a nightmare. Her head is constantly down, nose glued to every scent she finds...in the past, when she was having a good old sniff at something...and I wanted to walk on I would 'click-click' like you do with a horse and she knew it was time to shift. She's such a sweetie, but if i pull on her lead to get her moving...she looks at me so sadly...like I'm a puppy abuser 
She's only little so I can't easily reach her to get her attention with touch...I end up feeling like I'm dragging her along...trying to keep her head up...with her looking so sad...tail down...neck arched...going slower and slower...it's just not fun...for either of us...the more i try and 'pull' her along...the slower we go...I feel like a mean, old ratbag...cos' I start to feel a bit cross with all the stopping...then she looks so pathetic that I loosen up the lead...head goes down...tail comes up...we come to a halt.
I want her to have a good old sniff at stuff...reading her 'wee-mails' as I call it...checking out all the other dogs in the neighbour hood...but there is a limit. Any advice...please...I've never had a dog as old as this before...not sure how to handle things.
