Yes I took him to the best hospital got all his medical tests done. His ECG, As per results of medicals he was diagnosed with heart expansion,left atrium is enlarged. Yes his abdomen is large. been giving medications to him for that. He was doing fine since last 2 months but last week seems he is back to the same problem. Now he can't rest and sit.
Thank you so much. I will definately take him to his vet. And will let you know once get back.
