15yr old collie with an unmedicated grade 4 heart murmur (only known condition didn't want to drip feed) was only diagnosed at last check up and vet and I felt she was coping well and was without symptoms so no need to start medicating in such twilight years. Any way she is eating but within last week has dropped weight noticeably she is not really out of sorts in any way which makes me confused. She has always ate a mixture of raw and complete and been a bit hard to regulate weight as in she gets chubby because she steals my other dogs food, she is a complete glutton so we do monitor her food intake closely. She is normally a healthy 13-15kg which is good for her size and can normally feel her ribs and spine if pushing a little but if you shaved her now I think they would both be protruding she feels very Boney all of a sudden
.
I will take her to the vets but any ideas or others experience with similar to this would be helpful.
