As one who used to have 4 dogs that were (forcefully) given to my family, trying to play with some of them with some spare time isn't an easy task.
Why? Because if you playing with them with just spare time, you can't play with all of them which in turn makes others that weren't played with feeling jealous. And hell jealous dogs are troublesome, as they will fight each other or bark for some attention.
Sadly 3 of them passed away, so the last one is now in kind of depression... I would rather have 4 annoying and trouble loving dogs than 1 now depressed dog, be graceful Rinno.
