Last Friday I thought my boxer, Layla, has pulled/sprained a muscle in her shoulder. I took her to the emergency vet clinic where they felt that was probably correct. Last evening I was rubbing her shoulders from behind and noticed a definate swelling. Not being comfortable with this I took her to our regular Vet today and he feels it is a hemotoma caused by trauma ie running into something. The internet has a lot of info on hemotomas in the ears but this is left front where the upper leg joins the body. Has anyone dealt with this situation and how was it resolved?
