I don't like either.
Generally don't like pets, I like animals in the wild (on television, though I would do a Safari if the opportunity arose!) or in a zoo.
To put it in to very simple terms, all those Dog owners who say their Dog will not attack anybody, I'm sorry but I dont believe you, and I don't trust your stinking mutt either.
You cant bloody talk with your dog, I mean your dog might just be getting completely sick and tired of the food and flavour you are feeding him, and he/she just says to themselves.....
'Right for fucks sake, thats it, I have had enough of this shit, same fecking dinner everyday, what dont they think I want variety..Ok well we'll see.....If they feed me that shit one more time, someone is gonna get it, probably that little one in the corner over there that seems to have taken all the attention off me, actually when I think about it, the lack of variance in my food coincides with when that little fucker arrived!'
Next you have this

I dont like or trust dogs, because I believe they 'think' like us (in their own right however) and have 'feelings' too, but you cant REALLY cater to them.
As for Cats, is it me or do they actually think they are better than us?
