I am looking for advice or guidance from anybody who has experience of living with a mini with an enlarged heart. My 8 year old black mini bitch, Belle, had a lump removed from her ear before Christmas and, unfortunately, it was found to be an agressive malignant melonoma. She is back in at the vet's today having x-rays and fine needle aspiration of the lymph nodes to see if it has spread already. The x-ray of her lungs does not show any spread there yet so I proceeded with a further op to have her complete ear flap removed to give more margin around the original melonoma site.
If a melonoma wasn't bad enough, the chest x-ray has shown she has an enlarged heart and some degree of heart failure. I will be discussing options with my vet who has initially suggested medication and a cardiology referral.
Does anybody have any experience of their dog having an enlarged heart and if so what did you do? Medicate, ECG, referral, are there any side affects to the meds etc?
I know if the melanoma has spread the prognosis is very pooor and the heart enlargement will be irrelevent but I am trying very hard to be positive and hoping the melonoma has been contained. Any info would be gratefully received. Thanks in advance.
