I took Midas (my 3.5 yr old Black Lab/Golden retriever) to the vet several days ago. He had a lump in his right ear. I figured he had been bitten by some bug, but the vet said it is a Hematoma (Busted blood capillaries) in his ear, due to shaking his head because of an ear infection. He said it was small enough, that with treatment for the ear infection, to stop the head shaking, it should reabsorb itself. The thing is, that when I use the flush in his ear, it causes him to shake his head more trying to get it out. Sometimes it may require surgery on the hematoma. But the vet didn't think we should go that route. Unless of course that is what I wanted to do.

LOL the wife says the vet is a quack. She has had dogs all her life and never heard of it. I told her to google it and she'd find endless reports about it.

Anything that causes discomfort in the dogs/(any animal) ear can cause it to shake its head and cause this. Yeast infection or ear mites etc. It is good practice to use an oti clens to flush your pets ears or a weekly basis to prevent this from happening. The one I am using is a medicated mix to help with the infection, but the over the counter version is readily available to flush their ears.
