Getting our Rottweiler fixed
We have a 5 month old rotty, our vet has told us that getting her fixed at 5 months is very safe.
Then we ran into other rotty owners during our walks and they said getting her fixed that early can stunt her growth and end up with medical problems.
Getting your Rottweiler spayed before 6 months of age is safe, and it's one of the best things that you can do for her future health and wellbeing.
Having a dog 'altered' (whether it be a male or female) prior to 6 months reduces the chances of reproductive disorders - including cancers - enormously. It doesn't 'stunt growth' or cause health problems, those are 'old wives tails'.
Of course as with any surgery there are some risks, and possible, but rare, side effects involved and it's important to follow your vets' advice. However, spaying or neutering are simple procedures are beneficial rather than problematic.
Hope this helps, best of luck.
