K-9 Dinero (retired) needs your help

My retired Partner k-9 Dinero served 8 years protecting and serving as an explosive detection k9 for the Federal Reserve Police . I have been his handler for 5 of those years. Dinero has had quite a life as he survived bloat which I almost lost him to as well as being diagnosed with an heart arrhythmia which required him to be on meds for his entire career .  Dinero is now almost 12 and needs help even more now to continue enjoying his retired life at home with the family . 

He loves playing fetch in the yard and going on car rides ! Unfortunately now his legs have other plans and they are slowly giving out on him. Doctors suspect it’s degenerative myelopathy which has no cure ,but can be slowed down .  I’m asking for any help that we  get as medical cost and therapy cost are starting to climb . He needs an mri to confirm his diagnosis but due to his heart concerns we need to bring him to a specialist that can monitor him while under anesthesia . He also needs a wheel chair to help him with his walking.  I just want my boy to get the best care possible so please anything helps . 

I just want to thank you in advance for Helping my best friend get the care he deserves
