Help W/ Dog Food For My Service Dog

Good morning, my name is Brian Stone and I have a 3 year old long haired German Shepherd that is my service dog, and he helps me with balance and Mobility as far as climbing up and down stairs and if I were to fall he would go get somebody for me... I'm also a personal fitness trainer in West Linn and Lake Oswego and have had my own 3 personal training studio business for the last 20 years, but things have kind of taken a turn for the worst. I've had 16 Orthopedic surgeries and 8 broken bones and I was just diagnosed with rheumatoid arthritis and things are starting to slow down and I am in a lot of pain. Having such a large dog has really helped me as far as my balance but the cost of dog food has only raised by the month! So I am looking to see if anyone would be willing to help me out until I get back on my feet with helping me purchase Nulo salmon dog food? He takes 23 lb every two weeks and then I also boil chicken breast for him for every meal because Nico is not a food driven dog. I'm not one to ever ask for anything I am a very independent disabled person, I drive and like I said I am an in-home personal fitness trainer that has had huge results and have been on many new stations comment I hold a 1st degree black belt and gun Foo and I also hold two red belts in two other styles and was inducted into the martial arts hall of fame in 2009. I am a workaholic, and my clients mean everything to me and they actually become family... So like I said I am not one to ask for any help, I am just at my Wit's End and I have no dog food, or food for the week... So anything that would help would be much appreciated. Thank you and God bless you, Brian and Nico. Any little helps... Thanks again ☺
