<human>: Can you give me a shortened version of the text?

Hey guys. I have a 2 year old golden retriever and I'm 90% sure that he has ear mites. The inside of his ears have disgusting black goopy stuff encrusted in it and he scratches his head / shakes his head a lot. I told my parents and they don't want to "waste money" taking him to the vet because it is expensive.

My mom even suggested to put Chinese herbal infection medicine in his ears, but I told her this wouldn't work ("Why not!? It is safe for humans so it is definitely safe for dogs".) The last time we took him to the vet it was for a yeast infection in his ears, and the bill came up to be $220 and my parents grumbled about it for weeks. My dad likes the dog, but is convinced that "Dogs don't need to go to the doctor, they are animals and can survive in the wild". I tried to argue but it didn't work.

I'm very anxious. I can't afford to pay the vet bill by myself, not to mention our vet is kind of far and I don't have a car to take him there. Does anyone have any experience with ear mites and how I could treat them at home? What should I do? Any over the counter medications available at Petco or something?
<bot>: Pretty sure 2 year old golden has ear mites. Parents in denial and think vets are a waste of money. No car / funds to take him to the vet. How do I get rid of ear mites at home?
