Hi my dog Jerry is approximately 15 years old and has had a small soft mobile fatty lump on his chest for over a year. This week I noticed rather a flat, hard lump that was on the same side of his chest but very different in appearance and feel. It is more noticeable when he is laid down but can be seen when he is standing, it starts at the front left leg and is approximately 6" in diameter. It is very hard on feeling it and would appear to be on the outside of his chest wall but you can not easily feel the edges. As it is so large you would think that it would have been easliy noticable but I have no real idea how long he has had it, he has fairly long hair and with it being farily flat it is not that obvious.
I took him to the vets on Monday who told me it was probably a fatty lump and that I could have it biopsied but it would be expensive and even if it was a cancerous lump then it would be practically impossible to remove successfully as it was so large (it is approximately the size of a large hand diameter with fingers spread). I am at a loss what to do as I just feel that to leave it would be worse case scenario. I realise that he is an old boy and whilst relatively fit still, a large operation might not be in his best interests but I just don't feel reassured that to leave it and 'keep an eye on it' is in his best interests either. I do intend to take him back later this week to see a more experienced vet as the one I saw on Monday was quite young and seemed to be thinking on her feet as it were. Any advice would be much appreciated.
He is eating and drinking normally and his toilet habits are unchanged. In all other ways he seems healthy enough other than slight arthritis.
