If desired, you can try menthol sprays and other odor-masking agents to cover up the scent of a dog in heat. These sprays won’t cover the scent completely, but they do reduce it and may calm your male. You might need to try multiple scents and formulas before you find one that works for your particular dog.

Make sure that your dog is old enough to breed. A male dog usually reaches sexual maturity when they are over a year old, however they usually begin puberty when they are six months to eight months old. They can impregnate a female dog from the point of puberty on.

Male dogs are sexually active year-round and can be capable of siring puppies when they’re as young as 5 months, but they are most fertile after 12-to-15 months of age, once they are fully physically mature.

Dogs get stuck during mating because of a process called a copulatory tie. The male dog has an organ called the bulbus glandis, which is responsible for keeping him tied up with the female. The dog breeding tie basically keeps the semen secured inside the female dog.

2) Dogs shiver due to anxiety or fear. Thunderstorms, fireworks, travel, or any type of environmental change can cause dogs anxiety or fear. If your dog has severe shivering and anxiety in these situations, they may benefit from an anti-anxiety medication during the stressful periods.

Shivering and trembling may be symptoms of something serious — like poisoning, kidney disease, or injury. So, if your dog suddenly starts trembling or shivering, it’s important to take note of other symptoms such as diarrhea, vomiting, or limping. Then talk to your vet right away.

It turns out that both cats and dogs are able to detect menstruation by odor and hormonal levels. Of course, they don’t actually have any scientific concept of what’s happening in your uterus, but they do know that something is going on.
