i have 2 dogs both are males i have a miniature long haired mini doxin that is actually quite large for his breed and i have a 6 month old jack russel terrier now both have their ups and downs but they piss everywhere and the jack russel beats up on the doxing because he's so docile and takes it from the puppy because he's about 5 yrs old and kinda has the daddy mode to him but when he does get tired of it he does alpha dog him and throw his him around with no problems my mom and dad wanna neuter them both but i personally don't think it will stop the problems let me know what u think is best ideas
