If you’ve noticed that Rover has been scratching around his ears a lot more than usual lately, a bit of vinegar could bring him some big relief. Swabbing your pet’s ears with a cotton ball or soft cloth dabbed in solution of 2 parts vinegar and 1 part water will keep them clean and help deter ear mites and bacteria. It also soothes minor itches from mosquito bites and such. Warning: Do not apply vinegar to open lacerations. If you see a cut in your pet’s ears, seek veterinary treatment.
