“Would dog castration solve my dogs behavioral problems? Would it stop the wandering? Would it solve the problem of urine marking? Is it a struggle? Will my dog gain weight after the surgery? Would it reduce its protection ability? What other solutions are there for making my dog infertile?” Just a few of the frequently asked Questions about neutering male dogs. Although the topic is quite controversial, there are some proven facts that I would like to share a few thoughts about to help you in making this important decision. Let's see the most common believes and the truth. Belief #1: Castration will reduce the aggression level of my dog. Well, in some cases, yes. But only if the dog is trained well. If your dog shows aggression towards people or other dogs due to the lack of training and care, castration is not going to solve the problem. But in most cases it can reduce the sex-related aggression, thanks to the decrease of the hormone level. Keep reading... Belief #2: Castration will stop my dog wandering It will probably do, or at least it will reduce it. Since the reason for wandering is mostly to look for females, it is quite sure that your dog will be more likely to stay at home, but in some cases, mounting behavior may not stop, only decrease, mostly if it is a result of dominance. Belief #3: It will solve the problem of urine marking As territorial aggression decreases, urine marking will do too, most probably. According to a survey, urine marking reduced significantly in 50 % of the cases. Belief #4: My dog will get fat and lazy. False. Your dog might feel more hungry in the first times, but it only depends on you, if your pet gets overfed or not. There is no direct connection between the two. Belief #5: Chemical dog castration has the same effects as surgical castration, the only difference is that it is reversible. Almost. Chemical castration means that the dog's testicles are injected, which leads to the reduction of testosterone. It is reversible, but it has the same effects, the only difference is that unlike surgical castration, the chemical one does not reduce the risk of prostate and testicular cancer. Belief #6: Neutering reduces the protection abilities of my dog. Since protection is a natural instinct it is unlikely that your dog will protect your home in a less efficient way. It is a common misbelief, because territorial aggression decreases after castration, but it isn't in direct connection with loyalty and protection. Belief #7: The sooner the better False. Most researches show that neutering at a very young age (under 6 months) can cause several psychological and behavioral problems. After taking all into consideration, dog castration seems to be a lot less harmful than it first sounds and if you know that you don't want puppies from your dog for whatever reason, it seems to be the right thing to do. If you dread the idea of surgery, you can still go for chemical neutering or you can simply make sure that your dog does not get out if there is a bitch in heat nearby. Whichever you chose, preventing the birth of unwanted puppies is one of the main characteristics of a responsible dog owner.
