1. Yes and outside we have large wooodlands and grounds which he enjoys chasing "things" especially in the dark.
2. He does not cough at all and except for the laboured breathing is great but does tire more quickly which we put down to age.
3. For three months but it has been getting worse and is now very noticable
thank you for the advice. We will take him to the vet in the morning. It is just that living in France we wanted some idea of how to handle this problem. We did think it was a heart problem but it is good to be assured that medication might help.
Have taken Freddie to the vet where he was xrayed and fluid was taken from the thorax area and has been sent off for analysis. He has been put on a course of antibiotics until the analysis is received. Also on a low fat diet (though he is not overweight) as there was a lot of fat in the fluid that was taken.
