Not sure of the size limit, there used to be information about this but I can't find it. I typically downsize to 800 x 600 pixels, 75% quality, and that works well. Size is usually under 100 kb.
Agree with tanza, it's not good to overdo pain meds. An animal that doesn't feel the warning signal is far more likely to cause themselves harm. We want to protect them from discomfort, but at times that is absolutely the wrong thing to do.
Remember, a tired Basenji is a good Basenji… and also it is much harder to introduce a puppy to olders in the house... I would guess while you think he is "after" them... he just wants to play... you have to that that position... if they don't want to play with him.... Puppies play hard... usually adults will correct wild childs play... but they still need an outlet for all their built up energy...
