My Ruby is so unpredictable which dog she likes. There are no guarantees that she will not bite. I took her to the Basset Hound Walk in Stanley Park & she immediately recognized her own breed without hesitation. Sniffing her & Ruby sniffing them, but as soon as another type of dog she lunged for them. One man invited me over to meet Ruby. I was standing there with Ruby on her Gentle Leader about 2 ft. away. His Basset was a rather long haired type and barked just like a seal. As we were talking and without warning, she lunged and bit the dogs ear with blood and all. The guy's wife was crying and I am saying if you want to take him to a vet. The husband was calm about it all. The souvener t shirt that we picked up at the meet had a drawing of a basset biting the other one's ear. How appropriate!!!! Ruby is an super alpha female and just has to hump who ever she likes whether it's his head or ----. Oh and she is spayed.
