Rondos Medical treatment

2020 really sucks, yesterday I got the worst news from the vet after rondo has had trouble breathing and coughing, thinking it would go away after a week I took him to see the vet and they did bloodwork and x rays and determine the giant hearted rondo, my best friend had and enlarged heart which is causing his heart to beat faster than normal, now they want to do more test to see inside his heart (cardiac ultra sound) to determine what’s causing his heart to be enlarged, it could possible be treated, but at this time with covid and me not able to dj I’m stuck in a hard spot, and I’m not willing to let my best friend go, I’ve never been the one to ask for help but at this point I have no where to turn to and especially not knowing what the future holds with this pandemic, so I’m asking my friends or whoever can help, please donate anything u can, so I can keep rondo around, without doing this procedure, rondo might only have weeks or maybe months until his heart fails, if I get this done, weather it’s treatable or not at least I can come to peace that I tried everything I possibly could to keep the dog I’ve had since he was 8 weeks old, he turns 12 next week on December 12th, he’s been the healthiest dog his whole life and out of nowhere this came out of nowhere... all donations are welcome and thank you in advance
