What's the ideal age and weight for neutering my dog or puppy?

In small breed dogs some vets recommend waiting until the dog is older (6-8 months). The though is their lungs are better developed in an older puppy which makes the anesthesia part of the surgery "safer". That being said, many vets, including myself, have done thousands of neuters of dogs as young as 8 weeks or age with no problems. I think at 4.5 months he should be just fine to be neutered next week.

By convention, the general recommendation often 4-8 months, though early spy/neuter is common especially in shelters. A male dog who reaches sexual maturity before being neutered will grow into a “stalkier” build typically. There are also studies suggesting that waiting to neuter decrease the risk of knee problems and some types of cancers. However, he is also more likely to develop behavioral problems. With ages over 2, unneutered dogs are at a MUCH higher risk of overall health problems. I’d recommend talking to your vet about what their thoughts are. I don’t think there’s any significant difference in early neutering and neutering at 6 months of age. Here’s a couple of articles to consider: http://www.vrcc.com/oncology/does-early-castration-increase-the-risk-of-cancer-in-dogs/ https://www.petcoach.co/article/early-spays-neuters/ For what it’s worth, I don’t think it’s wrong to do it at 6 weeks and I don’t think it’s wrong to do it at 2 years. I DO think it’s wrong to just decide to NOT do it all together. I hope that’s helpful... I realize it may just muddy the waters more for you, and I apologize! Talk to your vet about what he or she recommends and the two of you can come up with the best plan for Diggy.

Great question! There are pros and cons to neutering at different ages, so ultimately it comes down to your personal preference. The biggest advantage of neutering around six months or so, is that this will normally prevent the development of problematic "boy behaviors" such as urine marking, wanting to mount other dogs, not getting along with other intact males, and wanting to roam constantly in search of female dogs. There is some evidence that early neutering (before the dog is finished growing) can increase the risk of certain orthopedic issues like hip dysplasia or cruciate ligament (ACL) ruptures later in life, especially in large-breed or very athletic dogs. So, this is something to take into account as well. Personally, I have always neutered my male dogs at around 10-12 months of age, when they're still fairly young but finished growing for the most part. Most of my clients choose to neuter around 6 months of age to avoid the behavior issues mentioned above. But ultimately, the choice is up to you :)

There are some studies that recently may have found a correlation between earlier neutering and an increased risk for joint issues. This is pretty new evidence and at this point I think it's not really clear what the risks and benefits are. I typically recommend waiting until a male dog has reached his adult size, usually around 1 year, to neuter BUT in situations where the dog is showing undesirable behaviors potentially related to sex hormones I strongly recommend neutering earlier. If you were planning on having him neutered by 8 months I doubt 1.5 months of growth would make much of a difference for his bones and joints, so I would considering scheduling the neuter now. You could always talk to your veterinarian about pros and cons as well.

Most veterinarians wait until at Least 6 months of age prior to neuter. As far as cost, all veterinary hospitals have their own pricing and it can vary based on location as well. I would encourage you to have him evaluated by a veterinarian soon to start vaccinations and deworming. The veterinarian you choose can give you an estimate for neutering at that time. If you don’t have a veterinarian chosen yet ask your friends and neighbors who they have used and would recommend. Best of luck and thank you for using Pet Coach.

There is still a debate on whether or not spaying / castrating animals at a later age is beneficial. For now, until more research is done, it is still recommended to spay female animals around 6 months of age. Some veterinarians will recommend spaying at a later age (12 months or more) due to the effects of removing hormones on the body causing stunted growth and other changes later in life. Castrating is recommended around 6 months of age as well. However, in my opinion, it is ok to wait on castrating a male animal until an older age. In female animals, there is enough research that has been done that shows spaying reduces the risk of developing mammary cancer and also eliminates the chance of getting a uterine infection (pyometra) which can be fatal. In my honest opinion, if the stunted growth theory were true, I would take a decrease in growth rate over mammary cancer. I have spayed and neutered hundreds of animals and I have not seen any complications (other than urinary incontinence in female dogs) from getting spayed or castrated. If you want to wait on castrating Red, I would be comfortable in saying that this should be fine but to consider castrating him in the future due to reducing the risk of testicular tumors and prostate issues. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further!

Having her spayed at 4 years of age is taking a big chance health wise, she will be in high risk of mammary gland tumors. i would personally recommend having her spayed at the age of 6 months, before her first period. changes you can expect is mainly weight gain, but as long as you are on top of it she should not become obese.
