Simba won’t chase a ball… at all…unless it’s in the garden/house and another dog wants it.
She’s a spoiled brat at times. I bought Simba a foam football hoping she would play with it and she showed no interest, until we had Shabba the staffy here and when Shabba started playing, of course Simba wanted it
Same goes with Oscar… “I don’t want it, but you can’t have it” ::)
There is one ball she likes actually… the one that distributes biscuits, she’ll spend hours rolling that around!
