How to Identify Common Pet Problems ?

Heat cycles can start as early as four or five months in a female kitten. Heat cycles in cats repeat every two to three weeks until the cat is spayed or becomes pregnant. Heat cycles may cause pain or discomfort in cats.
A cat`s first heat happens when she hits puberty at six to 10 months old. Her oestrus cycle will usually last four to five days and, unless she becomes pregnant, she will be in heat again in roughly two to three weeks.
Is a Dog`s First Heat Shorter? A dog`s first heat is typically between two and four weeks. The RSPCA said that while the average heat cycle lasts three weeks, some dogs could come into season as early as six months old and stay in season for just two weeks.
Each heat generally lasts several days with the average length being seven days, although it can range from 1 to 21 days. If the queen (an intact female cat) is not mated during estrus, she will go out of heat for a short period of time, usually about seven days, but it can range from 2 to 19 days.
Do cats bleed when they`re in heat? In the vast majority of cases, cats don`t bleed when they`re in heat, although it is possible. Blood in their urine or around the genital area could be a sign of a urinary tract infection, so if you do spot any blood, be sure to contact your vet right away.
A cat usually has her first heat at around 6 months of age, but some can have it as early as 4 months old. During a heat your cat may be more affectionate, rubbing up against furniture, walls and her favorite people.
Can you spay a cat in heat? Spaying a cat while they`re in heat is not ideal because during this time the blood vessels in their ovaries, uterus, and fallopian tubes become enlarged. This can make surgery more difficult and your cat`s recovery time longer.
Some cats exhibit what is called “silent heat.” The cats are in heat, they develop follicles on their ovaries and are fertile, but they show no behavioral signs of being in heat. These cats will allow a male to mate with them. Silent heat is more commonly seen in cats who are lower down in the social hierarchy.
Some signs of a female dog going into heat may include lower energy levels, more aggressive behavior, differences in leg-raising while urinating, urinating more often than usual, and even running away from home. This is unlike male dogs, who do not experience heat cycles.
The earliest sign of estrus is swelling or engorgement of the vulva, but this swelling is not always obvious. Bloody vaginal discharge is often the first sign that an owner notices when their dog comes into heat. In some cases, the discharge will not be apparent until several days after estrus has begun.
Cats on heat usually `call` (meow very loudly), roll around a lot, arch their back, and become extremely affectionate/flirty. Have your cat neutered to prevent unwanted pregnancies (ideally at 4-6 months old). Once your cat is speyed, she won`t come on heat or be able to get pregnant.
Extra Petting and Brushings During Heat Cycle

For some cats, a little extra attention may help ease the stress of estrus. Give your feline friend some extra attention around the home when she`s in heat, and you may find that it calms her down and keeps her stress levels manageable.

First, cats do not shed the lining of their uterus. So, contrary to popular belief, heat should not involve vaginal bleeding. If your female cat is bleeding, contact your vet. Because a human female sheds the lining of her uterus every month, cramping, bloating, and related symptoms can be present.
In felines it`s called `oestrus`, but many people just refer to it as being `in heat`. Only unspayed female cats go through these cycles but rather than shedding the old womb lining like humans do, they reabsorb it, so bleeding is a very rare side effect.
“When do cats have periods?” is an important question to consider, because knowing your kitty`s cycle will help you to identify why she is bleeding. Like humans, cats begin having an estrus cycle at the start of puberty, around the age of four to six months, and the cycle can last anywhere from seven to ten days.
Your female pet can become pregnant on their first heat cycle, as they are sexually mature. This is inadvisable, as they are not done growing and more likely to have complications associated with the birthing and be poor mothers.
When the heat arrives, not only can cats feel hot and bothered, they`re also more at risk of heatstroke. While cats often seek the shade to keep themselves cool, there are some steps you can take to keep your cat safe.
When a female cat is in heat, she is much more likely to spray in an attempt to let any nearby tomcats know that she is ready to be mated with. Due to such a short and constant heat cycle, intact female cats can cause both herself and her environment to smell like urine pretty quickly.
The evaporating saliva causes a cooling effect, similar to the way human sweat keeps us cool. Cats also have a pretty efficient cooling system through sweat glands in their paw pads. As their body temperature heats up, the brain will send a message to the paw pads to start sweating and this will help to cool them down.
Cats in heat can have many behavioral changes. This can include acting more affectionate or demanding affection and rubbing up against people and/or furniture. Female cats may roll around more and raise their behind when pet. Although less common, some cats may urinate more or even spray on surfaces when in heat.
If your female cat isn`t spayed and she periodically meows excessively, she may be in heat at those times. Female cats in heat typically become increasingly affectionate, rub against you more, purr, roll around on the floor—and meow a lot. This lasts four to ten days.
Most spay/neuter skin incisions are fully healed within about 10–14 days, which coincides with the time that stitches or staples, if any, will need to be removed. Don`t bathe your pet or let them swim until their stitches or staples have been removed and your veterinarian has cleared you to do so.
How Often Do Cats Go Into Heat? Once estrous cycles begin, cats may go into heat as often as every 2-3 weeks. Cats are seasonally polyestrus (also spelled polyestrous), meaning they can have multiple cycles during their breeding season. Breeding season would normally be during warmer weather and longer daylight hours.
Pre-surgical Preparation Before Spaying Or Neutering

Most vets will ask that you fast your cat — meaning no food, and in some cases, no water — for up to twelve hours prior to surgery. This is to reduce the likelihood that your cat will vomit during the procedure, which can cause very serious complications.

Q. Russian blue mix cat – usually velvet soft coat but hair on back hind qtrs. is thinning, remaining hair seems less velvety than normal
ANSWER : A. Changes in coat appearance can be caused by a number of things. In older cats, hair loss or changes in coat and skin confirmation may indicate a metabolic issue such as thyroid problems. Cats can begin to lose hair and may also show other changes such as weight changes or appetite changes. Blood work is usually done to check for this, and most pets do very well with a daily medication treatment.

Hair loss can also be caused by mites on the skin, external parasites or even skin and fungal infections. These may cause red bumps or sores to appear on the skin in addition to the hair loss and coat changes. Your vet can take a skin scraping of the area to check for mites and infections, and a preventive flea treatment can remove any external parasites. If an infection or mites are present, your vet can also prescribe an antibiotic or topical cream to treat.

After any treatment it may take a month or two for completely bald patches to grow back in. This is normal as the skin and follicles need some time to heal prior to beginning the hair growth cycle again.

Q. Can a dog’s diet be the cause of bloody vaginal discharge. She’s a small Maltese / poodle
ANSWER : A. Short answer is no. Long answer would lead me to inquire if she has had her first heat yet. I always recommend spaying a dog before their first heat as it reduces their risk for mammary cancer and pyometras later in life. If you elect not to spay her just realize that these risks exist as she matures. In the meantime she will go in to heat regurally and have bloody discharge and possible behavioral changes encouraging her to mate. I am available online if you would like to consult in more detail. I would be happy to answer any questions you may have .

Q. I heard that Labradoodles don’t cool off through their fur/skin, so short haircuts aren’t necessary for summer months. Is this true?
ANSWER : A. Dogs don’t sweat in as many places as humans, but there is some heat exchange that occurs through the skin. It will depend on where you live, what activities your dog partakes in, and whether shaving seems to help her.

Some dogs can have trouble growing hair back, so if you are very concerned about appearance I wouldn’t do it. Make sure you watch for signs of heat stroke such as lethargy and vomiting. Slowly acclimate the dog during hot months and do not take him/her out in the hot parts of the day. If you have any concerns about heat stroke, ask your vet.

Q. My cat is lossing a lot of hair she is 13 yrs old and been to the vet twice and had antibiotic and the next time steroid and advantage plus . I’m at
ANSWER : A. There are many possible causes of hair losss as I’m sure your veterinarian has explained to you. At 13 years old, your cat is in the right age-range for diseases of the thyroid gland to develop. Itchiness and hair loss can sometimes be a symptom of thyroid disorders. It may be necessary to have a full senior blood work up to check the thyroid levels and overall health of your senior cat. Other causes of hair loss include allergies to fleas and contact dermatitis (allergic to some chemical in the enviroment such as scented cat litter, air freshners, laundry products, floor cleaners, etc). Hair loss is a symptom of a larger problem and can be frustrating to treat. Try to get to the underlying cause.

Q. Vomiting hair balls…resembing a hot dog
ANSWER : A. Hair balls are not normal in dogs, as we think of them being in cats. Hair will most definitely cause full or partial obstructions in dogs, and that’s likely why you’re seeing the vomiting. They don’t digest well and tend to hang around in the stomach until the dog is able to vomit them out. They can certainly get so big that they can’t pass and can’t be vomited, and then they obstruct the dog.

The first thing is to figure out why your dog is consuming hair. Work with your vet to determine if there’s an underlying problem, like parasites or allergies, and then work on resolving that. Hopefully that will resolve the hair consumption.

It’s worth mentioning that occasionally licking and chewing are behavioral problems in dogs, but rule out medical causes first.

Q. Whenever I take my dog on walks he always barks at people and others dogs in my neighborhood. What should I do to resolve the problem
ANSWER : A. The very first thing to do is to make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a good, happy dog and one who is less likely to bark from boredom or frustration. Depending on his breed, age, and health, your dog may require several long walks as well as a good game of chasing the ball and playing with some interactive toys.

Figure out what he gets out of barking and remove it. Don’t give your dog the opportunity to continue the barking behavior.

Ignore your dog’s barking for as long as it takes him to stop. That means don’t give him attention at all while he’s barking. Your attention only rewards him for being noisy. Don’t talk to, don’t touch, or even look at him. When he finally quiets, even to take a breath, reward him with a treat. To be successful with this method, you must wait as long as it takes for him to stop barking. Yelling at him is the equivalent of barking with him.

Get your dog accustomed to whatever causes him to bark. Start with whatever makes him bark at a distance. It must be far enough away that he doesn’t bark when he sees it. Feed him lots of good treats. Move the stimulus a little closer (perhaps as little as a few inches or a few feet to start) and feed treats. If the stimulus moves out of sight, stop giving your dog treats. You want your dog to learn that the appearance of the stimulus leads to good things.

Teach your dog the ‘quiet’ command. Oddly, the first step is to teach your dog to bark on command. Give your dog the command to “speak,” wait for him to bark two or three times, and then stick a tasty treat in front of his nose. When he stops barking to sniff the treat, praise him and give him the treat. Repeat until he starts barking as soon as you say “speak.” Once your dog can reliably bark on command, teach him the “quiet” command. In a calm environment with no distractions, tell him to “speak.” When he starts barking, say “quiet” and stick a treat in front of his nose. Praise him for being quiet and give him the treat.

As in all training, always end training on a good note, even if it is just for obeying something very simple, like the ‘sit’ command. If you dog regresses in training, go back to the last thing he did successfully and reinforce that before moving on again. Keep sessions short, 15-20 minutes max, and do this several times a day.

Q. I have a 17 year old cat and he has been shedding a lot the past 3 years. Is there anything I can do. I brush him but he doesn’t like it.
ANSWER : A. Brushing or providing objects that your cat can use to brush himself on (such as a scratching post with a brush attachment) are often the best ways to remove excess hair. If your cat doesn’t like the particular brush you use, you may want to try a different kind, or even use a warm wet washcloth to wipe your cat down with instead. This will help get rid of some loosened hairs without being as “annoying” to your cat. If he is grooming himself a lot, adding in a hairball paste to his food or placing some on his paw will help keep the hair from forming into a ball or becoming problematic as he removes the excess hair himself.

If you are seeing patches of hair loss, or any other signs of illness in addition to excessive shedding, then scheduling a senior wellness exam with your local vet is always best to check for aging-related issues which may be causing hair loss or other symptoms.
