Here's how you can tell which part of the heat cycle your dog is in. Proestrus: The First Week of Heat. The first week of your female dog's heat cycle is known as proestrus.

When do lab puppies have their first heat. Estrus, or heat, is the stage in a female dog's reproductive cycle during which she becomes receptive to mating with males. At this time, estrogen levels first increase and then sharply decrease, and mature eggs are released from the ovaries. Ideally, your dog should be spayed before she enters her first heat cycle. Some dogs can go into heat as young as four months, while larger breeds may be as old as two years before their first heat. Responsible breeders never breed a dog on her first or even her second heat. The nipples of female puppies don't differ much from their male siblings, but just give it time. If your pup is spayed before her first heat, her nipples will not develop much, but if she is intact when first going into heat, the nipples will enlarge. The nipples of nursing dogs remain larger. An unspayed Lab will likely have her first season any time from six months of age onwards. The average age is between nine and twelve months. Some large breed female dogs won’t have their first heat until as late as eighteen to twenty four months old.

Some large or giant breeds see their first heat occur at around 18 months or even later. At this age, mating and pregnancy would certainly not be an issue. Other breeds, like Chihuahuas and Pomeranians, can have their first heat at around 6 months, and a pregnancy that early that would almost certainly lead to complications. Most of the female Labradors go into heat period for every 6 months since their first season. Actually, anywhere between 6 and 8 months is considered very normal. But this is not a norm and many female Labs who went into their first season at an age of 1 year will repeat the cycle yearly only once. Also, six months is not a magic age in that the first heat can appear anytime after six months, but your dog might not have her first heat until she is much older. The rule of thumb (this is a general rule and and varies by breed and among individuals in a breed) is that the heat cycle lasts 21 days--7 days coming in, 7 days when she is.

The good news is that once the puppy is free of worms, the body can heal itself and regain normal growth and development.

A bitch generally has her first estrus season, or heat, at between 6 and 12 months of age, most commonly between 8 and 10 months. Mating will produce a litter at this age, but she is immature, so it is important to guard against that potential. A female dog will normally return to season about every six months. Some. The exact age your fur pal will have her first period depends on her breed. It can happen anywhere from 6 to 24 months of age. Usually it occurs at the earlier end of the range for small breeds -- Chihuahuas, Yorkies and miniature poodles, to name a few. Medium sized dogs like Labrador Retrievers generally go into heat in that 6 month range, however it can be up to a year before they have their first heat. Large Breed Dogs. Owners of large breed dogs tend to be the ones that have heat cycle scares. That’s because large breed dogs may not have their first heat until two years of age.

The canine estrus cycle (commonly referred to as the dog heat cycle) occurs every 6 to 12 months. 2. A puppy can go into heat sooner than you think. Puppies have a lot of growing to do in the first 8 weeks of their life, and for many months after. Different breeds mature at different rates.

Meanwhile, Great Danes and other giant breeds may not have their first heat until they are two years old. However, every dog is unique, and some Great Danes reach puberty before they are even a year old. Often, dogs show none of the usual symptoms during their first estrus cycle. Most dogs have their first heat cycle at about 6 to 9 months, so I assume you mean months in your question not years. Female dogs are "in heat" for a period of 3 to 4 weeks.
