Someone calls them and says you abuse your dog or do they have to have more proof? Thanks!!

I'm pretty sure they need more proof. Not word of mouth, they'd probally check the dog for wounds, etc.

They have to have proof of abuse. Just like with the two legged kids.

They need proof - usually, they need to see the dog and the dog's living conditions and make sure everything is okay with the dog.

I think there has to be proof before they would take him.

if someone calls saying you are abusing your dog, then someone may/will probably come out and investigate. It may not turn into them taking your dog away right away, but it could lead to it..

If someone makes such a call, they´ll visit you at take a good look at your dog and its living conditions, if everything seems just fine, they won´t take your dog..

yes they can

If there is enough evidence suggesting the dog has been abused they can take it away, but usually they do a check and then let you know what needs to be fixed and come back to see if you've done it. They don't like to take people's pets if they can help them fix whatever problem is there.
