This two-month old Great Dane is beautiful!!! But I'm concerned about one of the statements the owner made ..... and believe me, I know about having cats and dogs in the same house !!!
The owner said something like how the cats push the dog aside, and see what's in his bowl, etc. (total cat behaviour). Anyway, the owner said that they give the dog a toy shaped like a cat, and it can take it's frustrations out on that.
Never having owned a Great Dane .... is there any chance the dog would get aggressive towards the cats?? I owned an 80-lb male Chocolate Lab, and my six cats had that dog trained in no time !!! He's been swatted more than once by them.
