Holy cow! My stomach was in knots reading the post about the "test".
We had two females for the past three years until my sweet Daisy passed away last month.
Daisy was 8 years older than Nikki and even though Nikki (our Rottie) outweighed Daisy by nearly 40 lbs., she never challenged Daisy one bit (if Daisy was drinking out of the water bowl, Nikki stayed away until she was done, if Nikki finished her treat first, she never approached Daisy for hers, etc.)- and STILL we never, ever put them in that position!!!!!!!! We made sure they BOTH had their own treats and that treats AND food were always fed far apart from each other so as to always avoid any possibility of conflict. I never, ever wanted to face a possible fight that led to injury (or worse) to either one of my dogs.
I am sickened that a "test" would be taken so lightly and cannot even imagine what would have happened if one or both dogs failed that "test".
