It`s normal for an unspayed dog`s vulva to swell during certain points in her estrus cycle, or heat. The canine estrus cycle has four stages: proestrus, estrus, diestrus, and anestrus. The vulva will begin to swell during proestrus and remain enlarged to varying degrees throughout estrus and diestrus.
An unspayed female dog will go into the heat or estrus phase for approximately three to four weeks once or twice a year. This is completely normal for your dog. The production of estrogen in this period causes the tissues to expand and face outwards from the vulva.
The first sign of a female (dam) coming “into season” is often swelling of the vulva. This swelling can occur a week before bleeding, or the day before.
Symptoms of pyometra include early warning signs of the animal feeling unwell, such as vomiting, refusal to eat, lethargy, increased thirst and frequent urination. She may also appear to be uncomfortable, because pyometra is a particularly painful condition for dogs, while being somewhat less so for cats.
Abnormal vaginal discharge (brown, green, black, or pus-colored) at any time during pregnancy, abdominal pain, and fever are all potential signs of miscarriage or infection. Additionally, some pets experiencing a miscarriage will have contractions and deliver stillborn puppies.
Dogs in heat tend to bleed for approximately a week to 10 days. Some dogs bleed very heavily and others so lightly that it`s barely noticeable.
Anal sac disease is very common in dogs. The sacs frequently become impacted (plugged), usually due to inflammation of the ducts. The secretion within the impacted sacs will thicken and the sacs will become swollen and distended, making it painful for your dog to pass feces.
Never scold your pup if she happens to make a bloody mess, just calmly reassure her while you clean it up. Make sure she`s eating well and drinking plenty of water. Provide extra potty breaks, as there is a lot going on down there and she may feel the urge to relieve herself more often.
What Are The Stages of a Dog in Heat? The dog estrous cycle is made up of four stages. These are the proestrus, estrus, diestrus, and anestrus. The proestrus is the most obvious stage, while the other stages are more subtle.
Heat usually lasts between 2-4 weeks. Early in the cycle, a female dog may not be receptive to male dogs, although some are receptive through the entire cycle. It can be shorter or longer and you`ll know the cycle is over when all her vulva returns to its normal size and there`s no more bleeding or discharge.
When a dog is in heat (receptive to mating), her vulva becomes swollen, and a bloody discharge will be evident. This heat period usually lasts for a week or two but can vary widely between dogs. After being in heat, the bleeding should stop, and the vulva returns to its normal appearance.
Pyometras are categorized as “open” or “closed.” In an open pyometra, infectious material leaks from the uterus; owners may notice a bloody, yellow, or cream-colored discharge on their dog`s fur near the uterine opening or on their bedding.
If you suspect that your dog has miscarried, bring her in to the veterinarian. The veterinarian can test for the presence of fetuses through palpation, radiographs, or ultrasound, which will reveal any puppies that are present.
In addition to the shedding of the uterine walls, miscarriage at 5 weeks will also comprise of the pregnancy tissues. As such, the bleeding is normally heavier than a period. At this time, the embryo is not yet developed and no recognizable tissue will be passed along with the blood.
You may also observe that her vulva is large, red, or swollen with some bleeding or blood-tinted discharge. Your dog will only bleed for around half of the total cycle, usually 7 to 10 days. Generally, bigger dogs bleed more than smaller dogs, but it varies between dogs. Some dogs bleed very little.
The cycle often happens twice per year. The American Kennel Club (AKC) writes that some smaller breeds can go into heat up to four times per year, and extra-large dogs, such as St. Bernards or Great Danes, may only experience it every eighteen months.
False pregnancy is most commonly seen in female dogs (although cats may rarely be affected). Hormone changes after a `season` or heat convince her and her body that she is pregnant. It is sometimes called phantom pregnancy or pseudopregnancy.
The most common signs that your female dog may be entering heat are increased urination, changes in behaviour (such as being more clingy), swollen vulva, and bloody vaginal discharge. It is important to note that these symptoms can vary depending on the breed of your dog.
Female Dogs.

In some cases, incontinence may be caused by a weak bladder. This condition is referred to as weak bladder sphincter incontinence. Your vet may call it Urethral Sphincter Mechanism Incompetence (USMI). It is the most common cause of urinary incontinence in spayed female dogs.

Generally, female Chihuahuas will go into heat (lasting approximately 3 weeks) about once or twice a year. Here are the stages of a typical female Chihuahua`s heat cycle: Proestrus – The first stage of a Chihuahua`s heat cycle, Proestrus, may or may not be easy for owners to identify.
To help control external bleeding, place a compress of clean cloth or gauze directly over your dog or cat`s wound. Apply firm but gentle pressure, and allow it to clot. If blood soaks through the compress, place a fresh compress on top of the old one and continue to apply firm but gentle pressure.
The first signs your dog is in heat are the swelling of her vulva and bright red bloody discharge. This stage is called proestrus. “There will be lots of licking,” Nielsen says. A dog in heat can bleed for around seven to 10 days.
The first stage of the dog heat cycle is called proestrus. This stage can last from 3 to 17 days, but many dogs experience about 9 days in proestrus. The first sign of this stage is the swelling of the vulva. This is one of the best ways to spot the beginning of a dog heat cycle.
Starting when your female puppy is between six months and one year old, she`ll begin her reproductive cycle, or “go into heat.” During this 3- to 4-week period, she`s ready to mate and looking for dates. That said, every pup is different and your pup may be on her own timeline.

Q. What do whipworms in cats look like?
ANSWER : A. Whipworms are usually found upon inspection of the stool under a microscope as they can be hard to see macroscopically. Worms that are more common to see in the stool are roundworms (long spaghetti-like strands) and tapeworms (small rice-grain segments). However in large infestations they can appear as long, skinny, hair-like worms that are white or pinkish in color. Whipworms have a characteristic egg shape (they look like little footballs with knobs on the end) when looked at under a microscope and this is usually the way your vet determines if an infection is present.

If you think your cat may have internal parasites, bringing in a sample of his stool to your vet for a fecal exam is best. Your vet can then provide you with the correct worm type present and right type of dewormer to give.

Q. My cat has a little bit of blood in her ear, looks like she scratched it. It isn’t bleeding at the moment and it’s small. She is behaving normally.
ANSWER : A. I would keep a watch on it. Ear injuries are pretty common but as long as it looks to be healing and not infected I wouldn’t worry too much.

If the dried blood looks like it’s in the ear canal, it could be a sign of ear infection or mites. If this is the case I would have the vet take a look to confirm.

Q. My dog had very red gums. He is also eating grass. Is this normal?
ANSWER : A. Normal gums on a dog are usually a pinkish color, and can be checked for health by lightly pressing down on the gum until it turns white. When your finger is removed, the color should return within 2-3 seconds. In dogs that are anemic or ill, the gums will continue to be a pale white color for a long period. Gums that are blood red, or appear to be bleeding can indicate a problem such as a bleeding or blood clotting disorder, and can also sometimes indicate ingestion of a poison or toxin causing a bleeding disorder.

If your dog’s gums are actively bleeding or blood red, you think your dog may have ingested something toxic or poisonous, or he has other symptoms of bleeding, lethargy, or illness, it is best to contact your local veterinarian or emergency clinic immediately for treatment.

Q. my dog was bleeding from the rectum and had a big bruise on her inner thigh. she died and her poop was watery green.
ANSWER : A. I am not sure what your question is but I feel you are looking for maybe an answer as to why she died. 3 things immediately come to mind as possibilities. First- a trauma of some sort- fell down stairs, was accidentally stepped on, maybe she was out and was even hit by a car- this can cause bleeding from the rectum and diarrhea but usually trauma will have other signs especially of it was bad enough to be fatal. Second, an ingestion of a poison- specifically rat poison. These poisons cause rats, mice, dogs , and people to internally bleed. The bleeding from rectum, bruising and watery diarrhea could all be from that poison. Lastly, an auto immune issue that destroys platelets, called thrombocytopenia, could cause these signs and be a fatal illness. I hope this was helpful and sorry for your loss.

Q. Hello, I found a bag of food at Walmart named “Pure Balance”, it claims to be corn, wheat and soy free. I just wanted to check if it is good
ANSWER : A. Checking the full ingredients list can help to determine if the food you mentioned is appropriate for your dog. If it is free of common allergens such as corn, wheat and soy, look for alternative grains such as rice or oats. These grains are often much easier to digest. Looking at the protein source is also important- a good diet will usually have its protein source listed as the first ingredient. Ingredients are listed by the volume included from highest to lowest, but sometimes grains or other “undesirable” ingredients will be broken down into smaller ingredients to make it look like there are fewer of them. However if you see several grain products added together on the list, it may be more than the protein source! If you are looking to feed a completely grain free diet, alternative carbohydrate sources such as potato, sweet potato and pea are good choices.
