Pls Help My Baby Chino :(

My baby chino is a GoldenChow (goldenretrvr and half chochow).

He is a funny and jolly little 5month old dog and ever since we make sure that we taking care of him.

Yesterday, we observed him looking so tired and didnt eat much. So we thought at first that was because he wanted to go out and play as we normally do but he didnt even want to get up and just wanted to lay down. Then we noticed that his heartbeat was getting faster so we thought that it would led to a heart complication. We went to VET to have him checked but after that due to lack of financial because of the emergncy happened to my mom and dad weeks ago, I couldnt push through the another set of exams and tests that the vet (doc) was advising us to do next. He (doc) said that it could be anaemia but his not really sure because wer not doing the exam/test yet. He just gave us the receipt of how much it will cost not including the vitamins and medicines.

I am really down but still looking forward for possibilities. It is somehow traumatic because of what is happening right now for my mom and dad's health who just had a stroke and now, my beloved dog Chino who was one of the great motivators to me is also suffering from health issue.

I missed his jolly and funny moves. I missed his tail wiggling and his joys to his eyes.

Please help me save my dog :(
