dog is not an issue here..think shes not ready/ dont want to be a mum..
having kids aside, hows your relationship with her? do you feel any love from her? how do you treat the dog? if cold, would have been a major turn off for her..hence not wanting to have a kid with you..there is a real difference when you see/treat a dog as a dog vs treating a dog like a family..big difference..my wife is a dog lover and i know..if i would have seen a dog just like a dog, my marriage would not have lasted..it is important to love what she loves esp when it comes to animals..

if no love from her, better to divorce and move on..or else start treating her dog like a kid, she will slowly fall for your charm and be ready to give you a kid
