Erm.. *feels put on the spot*
Ok, the most obvious... Filas have an aversion to strangers. They just don't like anyone outside of their family and BELIEVE it when people say Filas have to be introduced to those who will be around a lot before their ojeriza settles in. Even when trained and taught who and what is acceptable, a Fila is very much their own dog and they follow their own instincts.
They are intimidating. A friend came over a few weeks ago, she was to stay with Buddy and Banzai while we left for the day (a looong day) and Bella was going with us. Bella was in her face and this made my friend very nervous- but Bella was just checking her out, lol. She stated she was very intimidating- and she is. She DEMANDS and DESERVES respect.
For example, my mom came to visit- it was horrible, bella wouldn't let her do anything without being under Bella's watchful eye at ALL times and even then, when mom did something that was unacceptable, bella's growl and grumble was let loose. Another example, though, my best friend came to visit and Bella was fine with her. You have to learn to trust a Fila's instincts as well.... if they don't wanna do it, don't make them.
ER visits... there has only been a couple, but they have been very stressful on all of us. If in real pain, Bella has to be sedated to even be seen and that's with both hubby and I in the room with her. Normal vet visits go well, even the specialist visits... bella has commands that she's told and she's pretty cooperative, but a change in a vet (like we've just experienced) is detrimental to MONTHS of hard work we went through to get her acquainted her with her vet.
Strangers-- they just don't understand. We do take Bella out with us when we can, like to the pet store or whatever....and she always gets people's jaws dropping and comments like "ohh, she's so pretty" as they advance. You have to be quick on your toes and be clear and strong in your voice when you say NO, you may NOT pet my dog.
Traveling- make sure your plans involve your Fila. There is no boarding place, no vet boarding, that would be safe for your fila or the people that would need to handle her. Every vacation we have planned has to involve at least Bella. Our anniversary plans? They included a night at a hotel in which she could stay, lol. We had to cancel those as we had to move her surgery up, though...
They are very devoted to their family- right down the cat, lol. Do not mess with her family, do not pose a threat.
Ok, that's all I can think of now, of course there is so much more.. if anyone has specific questions maybe they can ask.
