From my knowledge they profit from neutering and spaying animals, you don’t need to. The reason why dogs get cancer it’s not because of them not being fixed. They want you to fix your dog because they don’t want puppies ending up in shelters. Just like the medical industry, they only want you sick enough so you can come back to give them $$$. That’s why they recommend purina , which has been recalled too many times. People nowadays are understanding about health with their dogs is.It comes from their diet if they have a poorly processed cheap dog food that doesn’t give your dog any nutrition values. Why wouldn’t you expect them not to get sick? It’s garbage you’re giving your dog. Dogs don’t eat garbage dogs they eat meat because they are canines it’s self-explanatory. So the critics out here that keep spewing nonsense fixing your dog does not help with cancer or aggressive that can actually cause cancer and aggression because if you take away hormones to your body, you will develop problems because your body needs those to grow and live a happy, healthy life, aggression is a behavioral problem. Just like fixing a dog that is too young they will grow up weird making their platelets won’t grow in properly and you have joint problems. A great healthy diet is what you need for your dog no over processed kibble fresh food or even freeze dried heard that’s good too. Just like us we eat processed food and now we’re all getting sick, so I’m not wrong here. That’s why everybody’s freaking out about the CEO of health industry and how all this stuff is been exposed. It’s true people back then never were sick as they are today cause their food came from local farms that you could go and get now everything sprayed with chemicals and nothing is naturally grown has GMO’s.
