A bloody discharge from the vulva is a normal part of a female dog`s heat cycle. Dogs typically go into heat and bleed between 1-3 times a year. However, if your dog has been spayed or you know it is not time for your intact dog to go into heat, the bleeding could be a sign of a potentially serious health problem.
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.
Dogs with closed pyometra become severely ill very rapidly. They are anorectic (will not eat), listless, and depressed. Vomiting or diarrhea may also be present. Toxins released by the bacteria affect the kidney`s ability to retain fluid.
Prompt care is also recommended to relieve symptoms of discomfort and to start antibiotic therapy as well as making sure a more serious illness is not present and causing the bleeding. An infection of the uterus, called a pyometra, can also cause bleeding and mimic the symptoms of a urinary tract infection.
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.
Pyometra is a very serious infection of the womb, also known as the uterus. It`s caused by the womb filling with pus and, if left untreated, it can lead to kidney failure, toxaemia, dehydration and, in some cases, death.
The initial stage of pyometra usually comes with a slight vaginal discharge with no prominent symptoms. Pets diagnosed with pyometra later show visible signs. Dogs with pyometra also have an increased white blood cell count and globulins in the blood. Some dogs may also have painful, enlarged abdomen.
If there is discharge from the cervix or a bloated abdomen in an older female dog that has not been spayed, these are indicators that diagnostic tests should be done to confirm whether a dog has pyometra. Diagnostics would include a blood test to look at the white blood cell count and level of globulins in the blood.
The prognosis for dogs with pyometra is generally good if treated early and most dogs make a full recovery. The mortality rate following surgery is 5-8% and increases dramatically if there is a uterine rupture. If pyometra is left untreated, it can be life-threatening due to uterine rupture and sepsis.
Pyometra most often occurs in the weeks following a heat cycle, as hormonal changes create the opportunity for infection. Pets typically become ill very suddenly and although their clinical signs can be severe, owners don`t know what is wrong.
What is pyometra in dogs? Pyometra is a serious womb (or uterus) infection in dogs. The condition can be life-threatening and requires urgent veterinary treatment. The infection can cause your dog to be unusually tired, unwilling to eat, have an unquenchable thirst and have vaginal discharge.
If pyometra is not caught and treated in the early stages of the infection, the female dog`s uterus will rupture, causing the pus to fill the abdomen. If this happens, the prognosis is poor, and the animal will have only 24 to 48 hours to live if not properly and effectively treated.
Overview of Canine Metritis

This uterine disease is similar to pyometra but it has some differences. Unlike pyometra, metritis is most often a bacterial uterine infection that develops in the immediate post partum (after giving birth) period and occasionally after abortion or breeding.

Pyometra most commonly occurs in females >6 years of age, however we have also seen the condition in younger dogs, and occasionally in very young female dogs. It is most commonly diagnosed 1-12 weeks following the dog being `on heat`. 1 in 4 undesexed female dogs will develop a pyometra during their lifespan.
Dogs with pyometra will often stop eating or eat less; they may also drink less, causing them to become dehydrated. Vomiting is also a common sign, which can make the dehydration worse. A dog may also look bloated with a distended stomach.
If treatment is not performed quickly, the toxic effects from the bacteria will be fatal. If the cervix is closed, it is also possible for the uterus to rupture, spilling the infection into the abdominal cavity. This will also be fatal.
Conclusion. Dogs with closed cervix pyometra were more severely affected by the disease compared to dogs with open cervix pyometra as indicated by the more common finding of sepsis, leukocytosis, neutrophilia, monocytosis, and having moderately to severely depressed general condition in this group.
Pyometra is likely to return without surgery. In some cases, your vet may want to hospitalize the dog so they can monitor it during in treatment. In other cases, you may be allowed to treat your dog at home. If your dog is severely ill, it may need surgery to survive, especially if it has a closed cervix.
Pyometra may occur in young to middle-aged dogs; however, it is most common in older dogs. After many years of oestrus cycles, the uterine wall undergoes the changes that promote this disease. The typical time for pyometra to occur is about two to eight weeks after oestrus (“heat cycle”).
Just in case you are wondering, humans can get pyometra, however, it is extremely rare.
Pyometra, a purulent infection of the uterus, is a rare cause of a very common complaint—abdominal pain. Risk factors include gynecologic malignancy and postmenopausal status. The classically described presentation includes abdominal pain, fever, and vaginal discharge.

Q. My Bulldog puppy growls, barks and even tries to bite me when I say “no” to him. What can I do?
ANSWER : A. First, avoid scolding him and acting aggressively towards him if you don’t want him to be acting aggressively towards you. There are other methods you can use to communicate to your dog that you don’t want him to continue doing what he is doing. I recommend you stop telling him “no”, scolding him, or raising your voice at him. Everything coming from you should be 100% positive and 100% calm.

Try to figure out ways to clearly communicate what you want to your dog. If you want your dog to leave something or someone alone, I strongly suggest teaching your dog commands like “leave it”. Here is a link to a video in which I explain how to do it:

www.youtube.com/watch?v=R1TS5nA7z5Q

Another thing I suggest you use is a no-reward marker. This clearly communicates when your dog has done something wrong. No-reward markers have to be introduced during your training sessions. You should be doing at least three training sessions per day, that are something like 3-10 minutes long (working on different things each training session). If you are teaching your dog something BRAND NEW, do not use the no-reward marker, as you do not want to discourage your dog from performing behaviors for you. Use the no-reward marker for known behaviors only. Here is another helpful video about this:

www.youtube.com/watch?v=sdU5a6fXKlg

Lure each new behavior (as shown in the video) using high value treats. Let’s say you’re working on “down” which is a behavior your dog knows fairly well. Present the treat to your dog. Ask your dog to “down” (only ask once). If he does not go “down” immediately, say, “uh-oh” or “eh-eh” in a gentle tone, and then place the treat behind your back. This communicates to your dog that they did something to make the treat go away.

After you place the treat behind your back to show your pup “that was wrong” you need to communicate to your pup “let’s try again” by getting your pup to walk around for a second, and then start the behavior all over again. If your puppy is very young, chances are you haven’t taught him a solid “down” behavior yet. So, as I said, do not use this method until you have lured each new behavior as shown in the video.

This is the order in which you should teach behaviors: Lure using a high value treat as shown in the video. After a few successful food lures, lure with an empty hand. If the pup is successful with the empty hand lure, reward with lots of treats. If the pup is unsuccessful, then go back to food-luring a couple more times. After a few successful empty-hand lures, you can begin to add the cue. Say “sit”, then lure with an empty hand, and then reward. Once your pup understands the cue, begin to work on the no-reward marker.

Q. Have a dachshund who is over weight but this past couple of days she refuses to go up steps and her left back leg is not being used, and she is guntin
ANSWER : A. This particular breed is very susceptible to back problems. Your dog is showing some classic symptoms of back pain- reluctance to climb stairs, weakness or inability to use a rear leg and grunting. Your dog should be examined and have radiographs of her back as soon as possible. Hopefully, she can be treated medically, but sometimes back problems progress quickly to something surgical. The quicker you get an accurate assessment of the extent of her problem, the quicker you dan get her some pain relief.

Q. What is the disease that affects vertebra on Boxer dogs?
ANSWER : A. There are lots of problems with the back that can go wrong , however one common one is Intervertebral Disk Disease (IVD). This involves a gradual degeneration of the pads between vertebrae that are used to help pad impact and protect the nerves inside the spinal cord. This can cause pain, trouble walking, paralysis and more. Many other back problems can include Wobbler’s Syndrome- a problem where the neck and back meet, or even just plain injury to the back itself. Boxers that have docked tails may also have nerve issues in the cauda equina- a group of nerves that meet at the base of the back and tail and are important in proper function of the lower organs, tail and legs.

Q. My Chihuahua was jumping and suddenly started whining. Now she won’t put her hind leg down, but doesn’t cry when I mess with it. Will it heal on own?
ANSWER : A. Leg injuries are very common in small dogs, especially if they have jumped from a high place, or even stumbled and landed on the leg wrong. Leg injuries can be caused by anything from minor sprains and strains, to full blown breaks or joint tears and even arthritis or luxating patellas (knee joints that slip in and out). If the leg appears swollen, dislocated or there is visible bone or bleeding, veterinary care should be sought. Providing strict kennel rest and decreased activity for a day or two can help with minor injuries, however if the limping continues for more than a day you should make an appointment with your local veterinarian.

Q. One of my pet’s ears seems very irritated. What I can use to clean it with?
ANSWER : A. Ear Irritation can be caused by a number of things ranging from allergies, ear infections or even mites. Dirty ears can also cause irritation and problems. Knowing the type of problem is best for figuring out how to treat it.

For plain dirty ears that do not have any odor, redness or leakage of discharge/debris, a simple over the counter canine ear cleaner can be used. Gently soak some cotton balls or a washcloth with the cleaner, and then use these to wipe out the flap of the ear and opening to the ear. Do NOT use Q-tips as these can become stuck or lodged in the curve of the ear canal and may cause injury to the ear drum.

If the ear is bright red or itchy without any dirt or debris in it, it may indicate an allergy. Sometimes an allergy medication can help provide relief in this situation. Your vet can give you the correct dosages of an over the counter allergy medication to use, or may recommend one specifically for dogs.

For infections and mites, changes to the ear such as bad smell or lots of debris and discharge, flecks of black or brown debris, or scabs and sores in the ear may be present. In these cases, it is best to have your vet take a sample of the ear debris to test for mites or infection. Your vet can then give you an ointment that is placed and left in the ear between ear cleanings. Most vets will then recommend cleaning the ears twice daily and then leaving in the ointment after for a period of ten days.

Ear mites ARE contagious to other pets, so if your dog does have them, it is best to treat any other pets in the house at the same time to prevent the mites from spreading around continuously.

Q. Are cottonelle moist wipes (designed for humans) safe to use on puppy’s fur?
ANSWER : A. While ingredients of this product are not easy to find, it seems that if the product is safe to use on humans for wiping, it should be OK for use externally to clean off dirt or debris on the fur.

It is best to try a small area of skin to try the product on first, and then watch for any reactions. Signs of adverse reaction include itching, redness, rash or irritation at the site used. If any irritation is seen, use should be discontinued. If no irritation is seen, it should be OK to use the wipes on a larger part of the body.

Q. My cocker spaniel can’t seem to get on her back feet and it looks as though her back is arched when she is just standing and she is shaking as though
ANSWER : A. I recommend you get her checked out right away. It sounds like she has back pain, and potentially she’s showing signs of some neurologic dysfunction (not being able to use her back legs properly). If she has “slipped” a disk there’s a very short window in which medical intervention can help. An emergency vet (I’m assuming it’s New Year’s Day where you are) will be able to assess her neurologic status and provide the appropriate treatment to not only treat her pain but hopefully restore her neurologic function.

Q. Are heart murmurs in a cat serious? He can’t use his bac legs?
ANSWER : A. If you cat suddenty lost ability to walk on back legs you should take him to your vets without delay as it could be related to heart disease. It may be a blood clot from the heart blocking blood supply to back legs.
