not really the jags/wolf jags all look the same and we have 5 total...all they do is fight among themselves same with our wolfs thats y i want to rehome them.the 2 wolfs fight with each other and the jags all fight with each other but thats really it. i would think a female jag would be less aggressive then a male jack from my experiance...our jack fought with everyone. the only thing i think would be in danger would maybe be the firmouth but no more then he is now
