The ability to hold the leash does not mean she has the range of motion to reach or even grasp the can.
I’ve seen service animals in action and they are pretty dang awesome. The change from being in work and at rest is also quite remarkable to observe. A true service animal has an impressive amount of training.
The service dogs in our area do a great job visiting schools & nursing homes. Amazing that some schools teach the children to read by having them read to the dog - who sits patiently & listens.
The joy on the faces of the elderly patients in the nursing homes is something to see!! Some never have any visitors at all. They love to pet & talk to the dogs & the dogs give them lots of love in return.
Animals are a great comfort to humans. They are wonderful, loving companions without asking much in return.
