Hi Ally and of course Dyson and Ruby
I hope Dyson makes it as your Assistance Dog... think of all the places he could go with you if he were. I can see him helping out with the weekly shop, enthusiastically working toward the pet isle.
Chester our last Goldie, was a Demo Dog as his hip dysplasia prevented him from being a full working Assistance dog. He was however - a great help to my mum around the house. He'd help take her socks off, picked up anything she dropped and loved bringing the shopping in.
Welly though, has not graduated to Chester's standards - he tends to try and eat the socks he removes!

And the shopping arrives in the kitchen rather battered and bruised

.
But Im sure Dyson is already a great help to you.
Good luck Dyson, keep us posted.
