Curious as to what you did to help your dog - while the other dog had a bite grip on him? While he was staring at you?
Punch or kick the %^%$ out of the other dog!!!! Pull your shoe off and whale the H&&& out of him - in the eyes if needed!!!!!
I would treat it the attack as if it were my son or wife.
ANYTHING GOES! LIFE OR DEATH!
Honestly, in my experiencing, beating the heck out of a dog, while they are in a fight, doesn't help. They don't feel it. They continue on with the fight. Your best option, in my experience, is to wait for that split second where one of them let's go and that split second always exists. While we tend to completely freak out and start screaming, kicking, throwing things, beating them with shovels, chairs, whatever we can crab, it doesn't help.
It is hard to stay calm in situations like these but you have to calm yourself and to stay cool and just go for that split second, grab the dog by the back and pull them up.
It is said to grab the back legs, however, personally, I grab into the back, right into the fur and skin, pull the top-dog into the air and once I've got the top-dog off I grab the fursaver as well. If she is still in the "kill-first or die" mode and wants to dive right back in, I choke her off and then put her into a down. The down is my emergency tool for pretty much everything and I know my bitch and know how she reacts and what triggers her.
She came out of heat and is very moody and over the top bitchy. Hubby let all the girls outside and she got into a fight with one of my other bitches. As long as I'm there supervising, everything is alright, but when hubby let's them out, poop will hit the fan because the dynamic is much different as if I am out there with them.
The key is to be calm, yet fast in your reaction and all I did was grab her at the behind, pulled her out, grabbed the fursaver and choked her off, then put her into a down, sent the other two girls inside and then lead Indra inside, examined her, went upstairs, crated her, put Nala on the table and examined her.
Throwing and beating is nowhere near as effective as keeping a cool head. If I had done that instead, the fight would have lasted a lot longer and caused serious injuries. But with a cool and calm head the fight didn't last any longer than maybe 30-50 seconds.
Anything goes, life or death, as if it was your wife.... KEEP A CALM HEAD ON YOUR SHOULDER! That always gets the job done faster.
THINK FIRST, THAN ACT!
