well... i bought my house which has 4 1/2 acres... eventually i plan on fencing the entire 4 1/2 acres, but for right now aproximatly 1/4 an acre is fenced with 5ft tall feild fencing...i also dont let my dogs out unsupervised. i obviously own the house so no worries about landlords opinions, i already checked with my homeowners insurance and theres no breed restrictions. my only close neighbor has a very dog frinedly APBT, so obviously the neighbor has no problems with bully breeds lol. personally i have experience with all kinds of dogs form itty bitty wowies to giant mastif and everything inbetween, i have worked around hard to handle breeds like sarpies and CAO's, as well as many bullies and mastif. im not worred about being able to handle any breed and infact am looking forward to having a more mentally challenging breed again. i did foster for a great dane rescue for a few years and my aunt used to breed them...but in terms of am-bulls and corsos, ive only worked with a few but thos e have worked with ive LOVED! i do have 2 small dogs with plans to add another chinese crested ot the mix sometime over the next few years...i am also planning on having livestock on my little homestead eventually. i KNOW theres no such thing as a 100% safe dog, all dogs are predators and must be trained to respect smaller animals, i also personally dont belive any dog is automatically dog agressive but understand some breeds do have a tendency towards dog agression...because of this i do want to make it very clear that i crate train and the big dog wouldnt be left loose alone around the little dogs or other animals. im planning on getting a male (because in my experience females tend to be more prone to same sex agression than males) and he will be neutered when fully grown. in terms of what im looking for in a dog: medium-large dog naturally protective (but not randomly agressive) eager to please strong desire to learn (stubborness is ok, im more than willing to work for it, but i would like to do basic ob and eventually hopefully get our CGC at minimum) VISUAL deterant...(a dog who would protect if properly trained is great, but i personally belive dogs are not bulletproof so i never rely on an animal of any kind as protection...however having a dog that makes most people stop and think...hmm, is it worth the risk? is what im looking for) incredibly loyal medium energy level, a good run around the yard and 2 daily 1 mile walks, occasional hiking/trail ride companion ect... low grooming drool and shedding is fine i know this describes pretty much any breed lol... in terms of breeds i like both the look and personality of dobermans, but ive rulled them out overall after being told by almost eveyr dobie owner ive met that they are highly prone to same sex agression....in all my years with dogs, dobies seem to get the worst reveiws by the people that adore them for same sex agression. cane corso, i love these guys, looks, personality...i do worry a little bit about their tendency towards dog agression, but im told as a breed they tend to be fine wiht the animals they are raised around American Bulldog, i fell inlove with chance many years ago when watching homeward bound and always loved the look of the american classic...ive not been around too many personally but am told they were developed as an all aorund farm dog...again can be dog agressive but again im told typically ok with the animals there raised around... great dane, i love danes, alot, but their short lifespan realy terrifies me, im so used to breeds that live 15+ years that such a short lived breed would just kill me... i like rotties but im so inlove with redyre rotties that i dont think i could settle for anything less lol and i know what that waitinglist must look like pressa canarios interest me but ive never worked directly with any bullmastif bouvier des flanders wolfhound mastif dogo i think of the list ive narrowed it down to the cane corso, american bulldog and Great dane...though i think in reality the corso and the Am-bull are my 2 prefered breeds simply because danes are heartbreakers... so id LOVE any personal imput on those breeds. in the future i plan on adding a couple of CAO's, anatolians, or Sarpies as LGD's but they would be working dogs... in terms of house dogs he would be the only "big" dog in the house.
