I use Tear Mender on Logan's ears. I started when I got him in May (breeder had done it prior to that). It holds well once it's set, but it's hard to get off without getting hair off, too.
Tear Mender
This natural latex non-toxic adhesive permanently bonds to leather, cotton, acrylic and other porous materials for a strong, flexible weather-proof repair. Use the included patching section or the patching material of your choice to form a waterproof, UV-resistant bond that will never wear out, or simply apply to a puncture or tear to seal the threads. Repair is fully functional within 30 minutes.
Wow - that sounds like real sticking. I even thought double stick tape and IPA clean.
