Is there a home remedy for fluid in a dog's ear canal?

My Border Collie has fluid in his ears. When you lift his ears and rub on his head you hear fluid. He also shakes his head a lot. I'm assuming it is in his canal. What home remedy can I do?

This may not be fluid, you may actually be hearing the cartilage moving. Is the ear red and hot to the touch? He may actually have an infection or ear mites? Or Has he actually been in the Water and your positive? He also may have allergies? Some simple solutions. 1. Take a cotton ball and put some acohol on it and the squeeze it into his ear. Hold him to the side to allow this to run down into his ear canal and rub his ear. You do not need a lot! If it is fluid, it will help to evaporate the H2O. Also kill ear mites. 2. If this does not work in about a few hours, then give him a child chewable benidril (my dog loves grape flavor). Check the package and follow the weight dosage. If you do not see an improvement, take him to the vet. It could be serious. Not knowing where you live and if there are other factors regarding what pollens are active, if your dog has been exposed to other animals (rabies), Does he have runny nose, eyes, etc makes it a guess, but this should be a start. Hope this helps.
