Update on Early Takeoffs in Dog Jumping
For those interested, we’ve been making some exciting progress toward understanding what causes dogs to take off for jumps inappropriately early. When I wrote the first article on “ETS” I stated that I suspected that a vision was a causative factor (please refer to my articles on this site for more information on ETS). At that time, that theory was hard to prove because affected dogs were being tested “cerf normal”. However a cerf does not test vision. Vision problems were likely present but not being diagnosed due to lack of appropriate testing. Veterinary ophthalmologists began using retinoscopy to test which did indicate refractive errors (near or farsightedness) in some affected dogs but not all. So, there still had to be other problems that were not being diagnosed. Just recently, we’ve had a human pediatric optometrist (experienced in testing vision with patients that cannot speak or read eye charts) begin evaluating dogs and, in addition to refraction errors, she’s been finding dogs with astigmatisms and depth perception issues using tests not apparently done in veterinary ophthalmology practice (vs research). More research is necessary to understand the significance but this is super progress and we are working with her to gradually gather more information. Stay tuned.
