How to Identify Common Pet Problems ?

Mathis: “If the clot is big enough to cause a full obstruction, they will just pass out.” Lungs: Clots that form in or embolize to the lungs cause acute breathing distress.
Symptoms of a blood clot include: throbbing or cramping pain, swelling, redness and warmth in a leg or arm. sudden breathlessness, sharp chest pain (may be worse when you breathe in) and a cough or coughing up blood.
In fact, some people don`t realize they have a deep vein clot until it causes a more serious condition. Deep vein clots—especially those in the thigh—can break off and travel through the bloodstream.
Things like liver disease, kidney problems, immune systems failures, toxins in a dog`s system, or hormonal disorders can also cause blood clots. The blood found in their poop might be coming from a clot, so it is essential to look out for the other symptoms associated with each of these ailments to know the cause.
If a clot plugs up veins in your arms or legs, they may look bluish or reddish. Your skin also might stay discolored from the damage to blood vessels afterward. A PE in your lung could make your skin pale, bluish, and clammy.
It takes about 3 to 6 months for a blood clot to go away. During this time, there are things you can do to relieve symptoms. Elevate your leg to reduce swelling. Talk to your doctor about using compression stockings.
Dogs for whom the cause of their pulmonary thromboembolism is trauma or generalized bacterial infection tend to have a better prognosis. Future episodes of pulmonary thromboembolism are likely unless an underlying cause is identified and corrected. These blood clots are often fatal, and sudden death is not unusual.
Long-term survival time varies between one month to several years with, the average being approximately a few months with treatment.
DVT Symptoms To Be Aware Of

Changes in the color of the affected leg – typically to a blue or purple shade. A warm feeling of the skin on the affected limb. Leg tenderness or pain. Tired or restless leg that doesn`t appear to go away.

Venous clots typically form slowly over a period of time. Symptoms of venous clots gradually become more noticeable.
Do I need to visit the vet? Loose runny poo with jelly like blood: this may be colitis (inflammation of the lower part of the bowel) – it should resolve in a couple of days, but some cases need treatment, so contact your vet if your dog is unwell or the symptoms persist or are severe.
When the colon becomes inflamed, it attempts to up its defences by producing even more of the normal mucus. So you will often find that your dog`s poo has a slimy consistency, or even looks like jelly. Since the walls of the colon are very sensitive to any insult, they can bleed quite easily.
It can cause pain, swelling, and red or dark, tender skin. The area around the blood clot may feel tight or sore like you have a muscle cramp or charley horse. Unfortunately, these symptoms of a blood clot can be confused with other conditions, including muscle pain and muscle injury.
While many blood clots dissolve with the help of blood thinners, some dangerous clots require fast-acting clot-busting medications called thrombolytics. Because thrombolytics can cause severe bleeding, doctors usually give them only to people with large, severe clots that increase risk of pulmonary embolism.
Most often, passing small blood clots during your period isn`t a cause for concern. The amount, length and frequency of menstrual bleeding vary from month to month and from person to person. But if you pass large blood clots that are bigger than a grape, seek medical care.
It can help prevent a heart attack or clot-related stroke by interfering with how the blood clots. But the same properties that make aspirin work as a blood thinner to stop it from clotting may also cause unwanted side effects, including bleeding into the brain or stomach.
A large clot can cause the lungs to collapse, resulting in heart failure, which can be fatal. About one in 10 people with an untreated DVT develops a severe pulmonary embolism.
While some blood clots are a normal part of your bodily function and will resolve on their own, others are more serious and can even become fatal if left untreated.
1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug.” 3) Activation of the coagulation cascade. 4) Formation of “fibrin plug” or the final clot.
This evaluation, known as Homan`s Test, consists of laying flat on your back and extending the knee in the suspected leg. Have a friend or family member raise the extended leg to 10 degrees, then have them squeeze the calf. If there`s deep pain in the calf, it may be indicative of DVT.
Recovery from blood clots in the lungs can vary from person to person. Many people recover in several months. During this time, they may need to keep taking medication to prevent additional blood clots. Sometimes, people need to take medication indefinitely.
A DVT or pulmonary embolism can take weeks or months to totally dissolve. Even a surface clot, which is a very minor issue, can take weeks to go away. If you have a DVT or pulmonary embolism, you typically get more and more relief as the clot gets smaller.
Statistically, about 84% of dogs with FCE will have a successful outcome. For large and giant breed dogs, the prognosis is more guarded if they are unable to walk.

the most relevant questions and answers related to your specific issue

Q. Has not eaten in 2 days. Noticed a little blood on the fur on her butt. What can I do?
ANSWER : A. Blood near the rear can be caused by a number of things. Bright red blood in the stool or around the anus can indicate a problem with the colon or anal region such as constipation, tears, illness or problems with the anal glands.

Blood that is dark or black in the stool can indicate a problem with the upper intestines such as the stomach or small intestine. This is usually considered more serious than bright red stool, however any blood seen is cause for concern. If the blood is seen more than once or twice, making a vet appointment is a must.

If your dog is not eating and is having blood in either her stool or vomit, making an appointment with your local vet is best. Illness, digestive upset or problems with internal organs can all cause these symptoms. In the mean time, a bland diet of plain boiled chicken and plain white rice may help to soothe minor digestive upset until you can get into the vet.

Q. I think she passed a blood clot.Is that possible?
ANSWER : A. It is possible but it can be also blood with mucous. You should see a vet because blood in stool is not a good sign and should not be neglected.

Q. Cat is over 13 years old, blood test show anemia, weight loss, increase appetite, thick nails, very vocal, blood test did not show thyroid disease,tre
ANSWER : A. It is possible another metabolic issue could be causing the anemia and weight loss, or a more in-depth thyroid test is needed beyond the basic panel. Anemia can be caused by a number of things including blood loss from internal or external bleeding, failure to produce enough blood cells, or destruction of the blood cells by the immune system. Looking for causes of anemia may help you to find the underlying cause causing your cat’s symptoms. Additional tests such as ultrasound, further blood work and more may be beneficial.

Q. Why does my English bulldog have re occurring urinary tract infection since she’s a 8 weeks and she’s 9 months now? And now they say she may have ki
ANSWER : A. As I’m sure your vet has told you it’s pretty unusual for a dog to have had multiple UTI’s starting at 8 weeks of age. I think it’s likely that she has a congential problem, which means something didn’t develop correctly inside or outside her body and it’s making her prone to the UTI’s.

There are a few bladder abnormalities that can contribute to UTIs, including urachal diverticulum (a little pouch or out-cropping of the bladder) and ectopic ureters (the ureters do not enter the bladder at the appropriate spot). On the outside, she could have a redundant vulvar fold, which is predisposing her to trapping fecal matter at her vulva, and the bacteria is ascending up to her bladder and causing recurrent UTIs.

The other possibility of that she got a UTI initially and it was never treated appropriately, i.e. The appropriate antibiotic wasn’t used and it never really resolved, but it seems like it’s coming back. I think this is less likely, as it’s really uncommon to begin with to see UTI’s in dogs this young. I also once saw a 4 month old dog with bladder cancer, but that’s incredibly rare and I think highly unlikely in your dog.

Your question got cut off at the end but it sounded like you were about to say that she may have kidney problems. If that’s right clearly this is becoming a serious problem for her.

Your dog needs a competent vet to work up this problem. It’s likely that she’s going to need some advanced imaging, including possibly an x-ray procedure called a cystogram and possibly an ultrasound. You might consider taking her to a veterinary internal medicine specialist at this point, if one is available in your area.

Q. My dog is snorting blood out of his nose. How can I stop this and do dogs get nose bleeds or is this a symptom of something worse.
ANSWER : A. Healthy dogs don’t get nose bleeds, it is always considered to be abnormal. There is plenty of possible causes. It may be something related to the nose itself (mass or foreign body in the nose, fungal infection, trauma) or the problem may be with blood clotting or very high blood pressure (the last one being the least common possibility). You should take your dog to your vets for examination, blood test and maybe nose examination like x-ray or endoscopy.

Q. My dog experiences extreme pain when jumping up on the bed or into the car.Sometimes when he launches into a run or gets excited he will yelp. Pano?
ANSWER : A. I’d agree that panosteitis is unlikely in a 2 year old dog, however it is possible. Luckily it’s pretty easy to diagnose. The pain is extremely obvious when the long bones are palpated from middle to almost end. Classically, the dog will be standing as you press along the bone, and then you’ll get to the spot with the lesion, and the dog will yelp in pain, or try to bite you. So I think if your dog had pano, you’d know it, and your vet would have figured it out.

If your dog has been through rigorous diagnostics like x-rays and blood work and no cause has been found, I think (unfortunately) it’s time to see a specialist. I’m really suspicious of a spinal problem, as they can be really difficult to find with routine examination and x-rays. A veterinary neurologist can perform a full neuro exam to look for deficits, and then if findings point to a possible spinal issue suggest imaging, possibly an MRI. In a dog as young as yours if nothing obvious has been found I suspect it’s in the spinal area. GSDs are predisposed to lumbosacral stenosis, so that’s where I’d start looking. Good luck.

Q. Our dog have cancer we had to get blood outside of his lungs now is is going anemic what would be your recommendation that we can do ?
ANSWER : A. It sounds like your dog is losing blood into his thorax. If that is the case, and there is no way to surgically stop the hemorrhage, then your options are limited. Your dogs bone marrow will kickstart to replace lost blood cells. If, however, your dogs anemia is severe, and him manufacturing of red blood cells is too small, then your dog will need a blood transfusion.

Q. My cat came in last night and fell over. Since then he is wobbly and appears to have pain in his left hind foot. I see a little abrasion on foot
ANSWER : A. It’s hard to tell from your description if she is just painful from an injury to her limb, or if he is exhibiting abnormal behavior possibly due to neurologic trauma. I think it would be prudent to take him in for an exam with your veterinarian. 1) you want to rule out any neurologic trauma 2) possibly administer an antibiotic if there is evidence of a cat fight. These wounds often turn into abscesses, and can lead to abnormal behavior if the bacterial infection gets into the blood stream 3) possibly radiograph the injured limb to check for fractures. I hope this helps.
