How old do female Rottweilers go into heat?
The heat or estrus period for female Rottweilers is usually between 6 and 12 months of age. This period of reproductive readiness lasts anywhere from 2 to 4 weeks. Female Rottweilers may become more attractive to male Rottweilers during this period and may even try to get their attention. You need to be aware that Rottweilers can become heat-sensitive and take the necessary precautions to avoid unwanted mating.
