This is beyond what anyone online can really help you with. Your dog needs to go to a vet, and soon. If money is an issue, I posted some hints a few posts down about how to help pay for vet bills.
But you really can't let this go on a lot longer. Please post back and let us know what you find out. I know what its like to worry about your best friend.
You need to take him to the vet. There are so many possibilities that could be wrong with him. Did you feed him any of the recalled pet food? Could he gotten into any poisons? It could be his time, the life expectancy for a golden retriever is 10 to 13 years.
Take him to the vet and Good Luck!
My young puppy just went through this and ended up being a stomach like flu he gave her some intestinal med to calm her stomach and after 2 days she's eats like normal
A golden puppy who is weak and not eating well - and been going on for weeks - needs immediate medical attention.
Has he had any teeth cleanings lately? This is close the age where annual cleanings are necessary to remove tarter buildup. Take him to the vet and they can check his jaw teeth along with many other things as there can be many things that can cause loss of appetite. Let us know how he is doing.
Please help me. My dog isn't eating his food and I do not have any money to take him to a vet. I saw that you said you would post something regarding this, but I didn't see anything. He also has mucous in his eyes, at first I thought it was parvo but now he is drinking water and his nose isn't dry at the moment. Can you please email me at ***@****.
