Both our Black Lab/Mixes have had ear infections of and on for quite some time! Just last week our 10 yr old Lab had rubbed her ear so hard on the carpet that she broke the blood vessels in the ear flap(it felt like a water balloon).
The vet had to drain the blood and stitch it. He said the constant itching could be due to allergies. What's strange is that when the 7 yr old has an infection, there's an odor. Never once have we noticed an odor w/the 10 yr old - just itching & shaking the ear.They've both been on Eukanuba Reduced Fat for about a year - when the constant problems seemed to start - before that they were on Iams.The vet said there could be something in the new food or possibly in the treats as I switched from Iams biscuits to Alpo, Recipe, etc. for variety. If anyone has any ideas I'd appreciate it. Thanks.
