Talk to them once, if they continue after that, I would call and file a complaint with SPCA. No animal deserves to be treated badly.

I would offer help and try to educate them. If that did not work I would call animal control. I won't watch animals starve or be treated cruelly.

I would talk to them, and then I would make an official call, definitely.

Time to make the call to the SPCA

I have called in the humane society

If talking to them didnt help, then call it in. No animals should be abused. In my family, we usually try to talk to them unless it really bad then my parents offer to buy the animals and get the care they needed. If they refuse to sell then we turn them in. Always remember the animal health and safety is the first and foremost in important.

I would confront them first... show them how to improve, and if they continue- report them.

I would probably just keep talking to them, and maybe volunteer to take care of the animals for them, or offer to buy them.

Calling is probably the right thing to do, though.....

That is a tough one...many times what one finds inhumane may fall into the letter of the law...if you decide to turn them in make sure they are in violation with the law in their care for the animals. Personally I would talk to them, offer help or to buy the animal..then do what I had to do. Many times when one does call the aspca they go in and if it is not too bad they educate and give the people the chance to fix the problem then if things dont change they then go in and remove the animals and charge the owners with the violations.

I have no issues reporting someone if they are truely neglecting their animals.
I reported a boarding facility that I felt wasn't taking proper care of the horses in his care.
Turns out the humane society thought he was doing an excellent job and that all the horses were fat, it was ok to feed them all their food in 1 feeding(they were only getting 2 flakes once a day), a 5 on the weight scale was fat, mud and shit didn't cause thrush, moldy hay wasn't a big deal they'd just pick through it, the list goes on and on and on that the humane society thought was acceptable. oh and that broken fencing wasn't a danger. This was all told to me by the officer that went out to see the place.
Everyone has their own standards and expectations. If the horse is in danger, skinny, sick, etc. I'd report them, but sadly a lot of the animal control people have no idea and if the horse isn't on deaths door they don't care.

I would talk to them the one time like you said but if it didn't make a difference I would file a complaint for sure! I have yet to come across a situation like that yet though :)
