Experienced and professional animal trainer provide their insights in answering this question :
A. Your dog could have a retained ovarian remnant. Sometimes dogs have “ectopic”, meaning not in the normal location, ovarian tissue. When they are spayed that tissue is left behind and the dog can continue to cycle. Unfortunately the only way to locate the remnant is to go back to surgery and look for it, then remove it.

After ovulation and breeding are completed, the progesterone level will continue to rise. The level typically rises to 40 to 50 ng/ml (the normal range can be 10 to 90) whether the bitch is bred, pregnant, or not.
The progesterone profiles of pregnant and nonpregnant bitches do not differ significantly; therefore, progesterone cannot be used for pregnancy diagnosis. However, progesterone levels above 2.6 ng/mL are required throughout the entire pregnancy to maintain pregnancy.
In the dog, the progesterone level will remain at this level for about 60 days whether or not the dog is bred, and whether or not she is pregnant. About 48 hours before whelping, the progesterone level drops to the 2 ng/ml range and within about 24 hours of whelping, the level drops to the 1 ng/ml range.
In other words, the fertile period in a canine begins two days after ovulation and lasts for the next three to four days. Progesterone levels rise between 4 and 10 ng/ml at the time of ovulation. While progesterone rises slowly before ovulation, progesterone levels rise rapidly after ovulation.
We know the progesterone level at the time of ovulation. However, at the time of breeding, there is no “ideal” level. When fertility is optimal, progesterone values might be around 10, 30, sometimes even greater than 60ng/mL.
Normal test results
In general, normal serum progesterone test results fall in the following ranges: men, postmenopausal women, and women at the beginning of their menstrual cycle: 1 ng/mL or under. women in the middle of their menstrual cycle: 5 to 20 ng/mL. pregnant women in their first trimester: 11.2 to 90 ng/mL.
A single ingestion of high doses of progesterone in birth control tablets is also unlikely to cause any toxicity. For iron-containing tablets, a dose of greater than 9 milligrams per pound (or 20 milligrams per kilogram) is considered toxic.
For most females, the best time for breeding is between the tenth and fourteenth day of estrus. However, some females ovulate as early as the third or fourth day or as late as the eighteenth day. It is normal to arrange for two matings (also called stud services) for your dog, often 24 to 48 hours apart.
After ovulation, progesterone levels go up for about 5 days before going back down. If pregnancy happens, your progesterone levels will slowly rise from the 9th week of pregnancy until the 32nd week. The placenta will begin to make progesterone after 12 weeks to help your pregnancy stay healthy.
1-6 days past ovulation
Sometime during days 1-6 after ovulation, progesterone levels begin noticeably rising. They start very low, typically at less than 1 ng/mL in serum. After an average of 3 days, a progesterone rise can be detected in urine, as progesterone heads towards its peak.
Progesterone is over 6.5 nmol/L (2 ng/ml) at the LH peak: breed 4–6 days later. Progesterone is over 16 nmol/L (5 ng/ml) at ovulation. Progesterone is over 25 to 30 nmol/L (8 ng/ml) at the start of the fertile period (LH + 3 days): breed 1–3 days later.
A c-section will be performed if labor fails to initiate by day 66 from the progesterone IR date measured during estrus or within 24 to 36 h after the progesterone level drops below 2 ng/ml.
Progesterone (P4) from the corpus luteum is critical for the establishment and maintenance of pregnancy and plays a major role in regulating endometrial secretions essential for stimulating and mediating changes in conceptus growth and differentiation throughout early pregnancy in ruminants.
Low progesterone can cause different problems for men and women. However, there are treatments available that can help resolve low progesterone. Hormone therapy may be a long-term solution for some, particularly postmenopausal women. Talk with your doctor about which treatment would be best.
Syndromes of hormone deficiency are often successfully treated by replacing the missing hormone, such as insulin injections to treat diabetes mellitus. Steroid and thyroid hormone replacements can usually be given orally.
Side effects may include increased appetite, increased thirst, weight gain, sleepiness, or changes in personality. More serious side effects include changes to the breast tissue, diabetes, decreased thyroid hormone levels, or uterine infection.
The progesterone test can be done every 2-3 days starting about 3-5 days into the heat. Timing of the test can be more certain if the lengths of the dog`s previous heat cycles are known. The beginning progesterone levels are typically less than 1.0 ng/ml until the day before the LH surge.
If your spayed female dog has a swollen vulva with a bloody discharge, it is possible that some ovarian tissue remained within her abdomen after her spay surgery. Infections, injuries, and tumors can also make a dog`s vulva appear to be swollen.
A: A dog is said to be in heat when they are in the proestrus and estrus stages of their reproductive cycle. During proestrus and estrus a dog will have bloody discharge from the vulva, and during estrus, a dog can get pregnant.
During the mid-luteal phase, serum progesterone levels are usually higher than 7 ng/mL. Some physicians have proposed using three luteal determinations with a total serum value of 15 ng/mL or more to indicate normal luteal function.
The prime function of the corpus luteum is to produce progesterone until the placenta takes over. Normal levels of progesterone can vary, even within the same woman from day to day. This can cause many pregnant women to worry about their progesterone levels during first trimester.
What Are Normal Results for Day 21. Low progesterone levels at Day 21 suggest no egg has been produced, eliminating the chance of pregnancy that month. Ideal levels register at 10 ng/ml, (nanograms per millilitre).
Typically, day 21 to 23 serum progesterone concentrations of more than 10 ng/mL indicate normal ovulation and concentrations below 10 ng/mL suggest anovulation, inadequate luteal phase progesterone production, or inappropriate timing of sample collection.

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. My dog has had dark red blood in stools for 2 days now . She found & ate a baby bird back in August , could that cause a problem now after so long
ANSWER : A. It seems pretty unlikely to me that the bird ingestion could have anything to do with the blood in the stool you’re seeing now. Depending on exactly how it looks, it could be a number of things. If the stool is normal and has blood on it, it could be an anal gland problem (infection, tumor) or a problem inside the rectum, like a mass. If she’s got diarrhea along with blood, she could have a bacterial or parasitic infection in her intestines, or she could have inflammatory bowel disease. I’d get this checked out as soon as possible.

Q. My dog is bleeding out of rearend after
going to vet for a leg trouble the vet says
it is stres
going to vet for a leg trouble the vet says
it is stres
ANSWER : A. It could be many things causing the problem. If it is an unneutered female it could be a season, if it is in the urine it could be a cystitis which could be set of by stress amongst other things. It could be from the anal glands or it could be from the lower intestinal tract. If it is the latter I would be careful what pain relief medication you are giving as some can cause bleeding in the GI tract such as meloxicam. I would recommend having a recheck with your vet to establish where the bleeding is coming from as some causes may require treatment or a change in current treatment.

Q. My 5 month old dog woke up today very lethargic and not very hungry. His feces smells very bad and it has an orange colored mucus in it. only 5 lbs
ANSWER : A. This could be many things, however first I’d ask you (if we could talk) if your puppy is vaccinated against parvo? That’s a serious viral disease that produces very bad-smelling bloody diarrhea. If he’s not vaccinated against parvo, please take him in to see a vet right away.
Otherwise, if he is vaccinated against parvo, he could have intestinal parasites, he could have eaten something that’s upset his GI tract, or he could have a bacterial infection, for starters. The orange color you mentioned has me especially concerned – I’m worried it could be blood. Regardless – he’s not eating, and he’s lethargic, so he likely feels pretty awful. I recommend you take him to see a vet right away who can figure out what’s going on and treat it appropriately.

Q. My male 2yr cat has blood in his pop
ANSWER : A. Blood in the stool can be a sign of serious problems. I would recommend taking your cat and a sample of the bloody stool into your vet for a check up. If the blood is “frank” blood, meaning it is bright, or red it could mean that there are issues with the colon. If the blood is dark, or more black in color, you could be looking at digestive issues. It is always important to alert your vet to any issues like this so that they can develop a treatment plan early. Good luck and I hope your kitty feels better soon!

Q. My dog started itching after being spayed. The dog was not itching before being spayed. She does not have fleas. The dog has had 6-7 dog bath shampoos
ANSWER : A. The bathing may be making the problem worse. Dogs should only be bathed if absolutely necessary. So tomorrow is the third day for injections, right? In that case I would be expecting to see improvements by tomorrow when you see your vet. If not then I would be asking for blood tests and depending upon the results of them she may need to be hospitalized on iv fluids. necessary as it strips the skin of its natural oils leading to imbalances which can cause dry, flaky or itchy skin. Leave off bathing for a while and if it continues then you needs to see your vet to establish the cause. It could be external parasites or allergies or a dermatitis. Treatment will vary depending on the cause. Medicated shampoos prescribed by your vet for a particular problem are ok but otherwise try to avoid bathing.

Q. My dog has dark runny feces. He is acting fine and eating and drinking normally. I read online it could mean internal bleeding but I don’t know
ANSWER : A. Usually blood in feces can show either as red blood (then it comes from the rectum or colon, or it is black and tarry looking (then it is digested blood from the upper intestinal tract). Runny feces are not normal. Let your dog fast for 12-24 hrs, then start feeding a blend diet (rice with broth, then rice with chicken, then slowly introduce his normal food). If the diarrhea does not cease, you need to take your dog to a vet. Bring a fresh stool sample.
