I have seen both sides of the spectrum and side with caution because taking action is faster than reaction.
Experience plays a big part in knowing your animals but I would not recommend attempting what people see in your pictures. Especially, someone new to keeping or adding a new pet to the mix. I have even seen animals with strong bonds get irritated and snap.
Love the pictures and always enjoy your post of the awesome looking animals.
Gatta agree with that had a friends dog never agressive always loving knew my brother well 1 day snapped and bit him in the face best we could tell he gave her a hug a little to tight that day even though it had never been a problem before
My bitbulls are more interested in the boas than my labs are. They pitbull love, smelling them, and one pitt likes licking the bigger boas. None of my dogs are aggressive with my snakes.
