[quote=Irena]all of them are dominate breeds can't say who's less depends on the dog himself i suppose[/quote] I know what you say, but there has to be a difference between these breeds. With some you have to put more effort to socialize with other people. I have hears that tosa and rhodesians are not so weary of strangers as typical guard breeds as the cc or the rottie. Also the dogo argentino is said to be more friendly. I would like to know whom is the easiest to manage around strange people and who has the qualities to be a better all around pet and most suitable to urban living and not so big places.
