i’ve been trying to make my mind up for a long time, i have experience with a few different dog breeds such as Chihuahuas, Bull Mastiff X Rottweiler and Alsatians and i helped my nan with her border collie (e.g training and walking)
but anyway i love bigger dogs they are much better companions in my opinion just i want a dog that i can let of lesh and will come back once called, will be good around smaller kids (my 2 little cousins love dogs also so it needs to be tough and tolerant with youngsters lol) isnt rediculously hard to train and has quite abit of energy as i enjoy jog/running and cycling. Needs to be a good guard dog.
Also on picking the breed which would be better female or male as ive heard many things like male dogs get on better with girls and like female rottweiler are more loyal when walking of leash etc but i dont really know if its true i thought it was to do with how they were brought up.
well anyways can you suggest the best of those 3 breeds for me and any other pros and cons of the breeds (besides illness’s i know about the history of them with these 3 breeds thanks :) )

thankyou everyone who answers xx

also i plan on taking my dog to a training centre :)
i know its not encouranged but i used to wrestle with my bull mastiffx rottweiler (he was like a red/brown rottweiler in appearence lol) all the time and he never got carried away and bite me id like a dog kinda like that :) playful and extremely loyal
IMPORANT: OUT OF ONLY BOXER AND ROTTWEILER NOW …..Thanks everyone xxx
