Best way I've found to post ears is from a website I found ..(kissmycocoa.com)
Great website and very helpful videos.
Love this method and is better than backer rod or tampons in my opinion. Of course I'm no expert and only have learned what ive found on the Internet so..
Appears to hold up amazing and doesn't seem to bother my dog's ears as much as the other ways which is always a plus!
Used 1 inch foam instead of 1 1/2 inch and worked well.
Going on my second week doing this and change it after a week. His left ear holds and then flops after a bit hopefully not too much longer of doing this ..hoping things turn out for the best for my red pup.
