Preventing unwanted pregnancy requires careful management when a female dog is in heat.
Separate Living Spaces: Use dedicated rooms, crates, or pet-proof barriers to keep the dogs apart.
Supervise Closely: Never leave them unsupervised, even briefly. Use leashes when moving them around the house.
Professional Help: Consider a dog walker or pet sitter if you can't be home, and consult your veterinarian or a trainer for advice.
Additional Tips: Reduce stress, clean up urine or blood promptly to minimize scent attraction, and maintain a safe distance at all times.
Even with precautions, accidents can happen. Stay vigilant and proactive to protect your dogs.
