My English Cocker Spaniels have also developed these fatty cysts. Mork, RIP, had a huge one growing under his front arm. They are usually benign. The vet just told me to keep an eye on it. Unfortunately the cyst grew very rapidly and when the vet took a needle test of the cyst, it was found to be cancerous. Mork not only had this cancerous tumor but had been suffering with arthritis. So, I had him put down.
The other Cocker, Mazie (Mork's sister) has started developing these cysts also. They do not hurt her nor bother her. I just need to keep an eye on them to see if they end up growing rapidly or not. If they grow rapidly, they MIGHT be cancer. So I just check her each week, daily would be too often cause you might not really catch any size changes. |
