As tittle say... a pet that we can set on FC outdoor that works as a guardian to keep out unwanted intruders... well maybe not functional as this last statement but yeah a pet that be able to intercact withmembers(and visitants).

If a member gets enough close to it: It act cheerful and happy (in the manner ocacional emotes or even follow him , would be neat if we can intercact with him via emotes too, like /petting or feeding it with special treats so he do special emotes/actions).

If a strange visitor enters the house or the yard; It chases him/her curious doing emotions to reflex this behavior.

And if SE ever implements a special Black List againts unwanted House visitors... this Pet would act all agresive barking or wathever else at them and annoy the hell out of them (it do be neat and funny to watch this really xD).
