What makes you think a dog would be much different. What I know, dogs likely need more attention and care than a pig.
Here we are again with someone grown past the novelty and like a closet full of toys, one more to put up for a new toy. So now, your innocent sweet pig has to pay the price because you want a lab.
Wow, I would love to have your pig and be sure it would have the best of care, love, and attention I can give, and I have all it takes for that except pigs are livestock in my city and can't keep them here.
Yes, I do know a lot of their behaviors and willing to accept those bad behaviors that just can't be trained out.
My rats chewed an expensive new shirt, can't blame the rats, that is what they do and I knew better,, My bad.
Still love my ratties, nothing changes there.
