He's looking good.. His wound looks just like Cadeau's did So don't be too worried, only a little A little leaking is good, as all the fluids are coming out of him so he'll heal better.

Oh did the vets tell you what causes many fatty masses?

In case they didn't explain it to you (just want you to feel at ease & understand it well) its a buildup of fatty tissues. It happens when a dog (typically of an older age) bumps into things & the skin separates from the meat. The fatty tissues collect in the little pocket & keep growing as it separates the skin from the meat. Its completely harmless to the dog, unless grown in a bad area. FOr Cadeau it was about to block her butt & the blockage would have caused real issues. The vet said they never remove them unless they are causing issues as they are more then likely to come back.. so its best to wait until they are a minor issue (as in effect the dogs comfort).

I hope this info helps put you at more ease & hopefully educates others too Fatty masses only create more dog to love.. they are kinda like doggy love handles hehehe Hope you like that little joke
