I Live in Cape Town South Africa and used to be involved with dog training . I helped by being a trainer before I returned to work after 18 years of being a stay at home mom. {I had 4 children!} . I had seen an article on U tube or somewhere where people with Parkinson's used dogs to help them pull themselves up from a sitting position. The dogs were big ! Like Great Danes and they and they acted as stabilisers and support for their owners. I was very interested and phoned up the Guide Dogs for the blind to be told that they had enough trouble getting dogs to train for the blind to be bothered training dogs for People with PD. So much for that! I must phone again and see if I can find a more helpful soul on the other end of the line!
I wish you good luck . I've never even met a PD person with a service dog! I'm very interested in how they are trained as I reckon a good dog trainer could do the job. How could a dog assist you? I'd like one to walk with me as I find my carers want to make me walk slowly and they want to hold my hand - which is not very helpful I feel. With a stiff handle like the guide dog's have I reckon I'd have as much support and be able to walk at a pace more my style - although I get out of breath now before I get to the first corner of the block! So much for old age!

A friend of a friend had a service dog that I was told was trained to help him when he fell. I don't know if that was to act as cushion, stepping in front of him when he was falling, or if it was to help pull him up. The guy didn't have PD, but had had cancer. The dog was a golden retriever.

Hi Pest, I applied a couple of years ago. The folks at the agency will find someone to train your pet or help you find a dog already trained. There was a $35 dollar application fee. I was stopped by the NP at the neurology office because she couldn't understand what special skills the dog would need or how they might help an owner with PD. As hard as the agency tried to help her understand, the NP never wrote the necessary letter so my application was not acted upon. I hope you are more successful in your attempt.

Below is the website you might want to visit for more information:
To get a service dog, the owner must meet several criteria. First, the owner must have a physical or mental disability that affects their day-to-day life and must be able to show that the animal can provide a service that benefits the person's specific illness.
