[help] How do I get my dog to listen without treats?

It's already her 2nd month here ( She is 4 months ) and she is starting not to listen without treats! Before she used to listen with or without treats, but now she seems to have a grown a " what's in it for me? " attitude. She does know commands such as Sit, Lie down, Up, etc. but will only do so with treats! She does them well with treats though, she responds quickly. Also another thing is that she is both treats and toy motivated, whenever I take her favorite chewing toy, she'd follow everything I'd say.Tips on getting her to listen without treats and teaching her how to would be very awesome, thanks! via /r/dogs http://ift.tt/2qSCn2D
