I had to have Harper spayed after a prolapse, and she's put on a ridiculous amount of weight. All her sisters are allowed to free feed, and Marley is far too thin. having cancer, Dash needs ever bit of nutrition. Would it be a good idea to seperate Harper until she loses the weight? How can I help her do that as far as her food goes since she's about as active as a rock? Maybe I'm making too much of this and should just accept that she's a mini beach ball? But I'm really worried for her health.
