Experienced and professional animal trainer provide their insights in answering this question :
A. Yes, there are injections to prevent pregnancy. It is usually given 2-3days after unwanted mating.

How to Identify Common Pet Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced pet care professionals :

Hormone injections: Hormone injections for female dogs are comparable to the contraceptive pill for humans. In the quiet phase after a heat period, the female is given an injection that must be repeated at the same time every five months.
Alizin® is a safe and effective drug treatment for mismating that induces abortion in dogs. It has a synthetic progesterone antagonist which blocks the signals that would otherwise allow successful ova implantation and subsequent maintenance of pregnancy. It does not affect future gestations or fertility.
Megestrol Acetate: Dog Contraceptive Pill

Initially developed to treat cancer and wasting syndrome in humans, megestrol acetate is also used as a birth control medication for female dogs. It is also used for treating a few other health conditions, including false pregnancy and some skin conditions.

Diethylstilbestrol (DES) and estradiol cypionate (ECP) are common morning-after pills for dogs using estrogen therapy to prevent fertilized eggs from migrating and implanting in the uterus.
It might take some effort to keep your dogs separate when your female dog is in heat, however, separating male and female dogs is the only surefire way other than spaying and neutering surgery to prevent them from bringing you a litter of puppies.
You might be tempted to try to separate dogs when they`re stuck in a copulatory tie during mating. But hold up: Pulling dogs apart can seriously injure them and doing so won`t stop a pregnancy from occurring. Instead, encourage your dog to remain calm.
Oxytocin (0.5–2 U in dogs; 0.25–1 U in cats) is given when uterine contractions are less frequent than expected for the stage of labor. The most effective time for treatment is when uterine inertia begins to develop, before the contractions stop completely.
ANSWER: Mismate shots are injections of long-acting estrogenic compounds. They probably work in three ways. First, they delay the transit of the fertilized eggs into the uterus. Second, they may cause a direct degenerative effect on the fertilized eggs.
Spaying and neutering your dogs is the best way to keep them from making puppies. There are health benefits for your dogs outside of not having puppies for spaying and neutering your dogs as well. Until they are spayed and neutered, you will want to keep a close eye on them to ensure they are not mating.
How many times should she mate to become pregnant? Answer: Once may be enough. However, to ensure that all of the eggs released by your Lab are fertilized, I always let my dogs mate every two days while the female will stand to be bred. Usually, it is 3 or 4 times.
Don`t do anything to try to separate the dogs, especially pull them apart by force, which could hurt them! Stay calm and wait for the dogs to unstick themselves. If they`re still stuck together after an hour (which is unlikely to happen), call your vet to get advice.
Your dog, just like all other living organisms that are set up for reproduction, has a natural inclination to mate. However, if your dog doesn`t mate, his life isn`t at risk. In fact, your dog, like humans and other animals, is not required to mate to live.
Not only are they not fertile, but their reproductive organs won`t open for penetration unless they are in heat so they can`t even engage in intercourse. If you discover that your female dog has engaged in intercourse, chances are that her heat symptoms were minimal or silent, so you did not realize she was in heat.
In short, your dog cannot become pregnant when not in heat, but many dog-owners have a hard time identifying and keeping track of when their pet is fertile.
Rather than leaving the dogs alone, you must stay present to ensure their safety. Simply sit back, be patient, and allow the dogs to do their thing, but be prepared to calm them down if they should become nervous or agitated. If you have never done this before, you may choose to have a professional breeder present.
Alizin is authorised to induce abortion from day 1 to 45 post mating although we recommend waiting to the end of oestrus before using the product to avoid the need for repeat courses. This is usually 10 to 14 days post mating. In the first trimester (up to day 21) the efficacy is 99.9%.
General Description: Misoprostol is used in dogs and cats to prevent or treat stomach ulcers, especially in pets taking NSAIDs. Other uses include: controlling allergic skin diseases in dogs (in combination with other drugs) and for the protection of the kidneys in pets taking the drug cyclosporine.
Oxytocin is a hormone that causes contractions of the uterus. It can be used to start labor or to speed up labor that began on its own. Contractions usually start in about 30 minutes after oxytocin is given.
Following intravenous administration of oxytocin, uterine response occurs almost immediately and subsides within 1 hour. Following intramuscular injection of the drug, uterine response occurs within 3 to 5 minutes and persists for 2 to 3 hours.
Estrogen, in the form of estradiol cypionate, is the traditional “mismate” shot, given to bitch`s shortly after unintentional breeding. This is not the technique of choice at this time because estrogen administration during heat in dogs may predispose them to uterine disease (pyometra) and will prolong standing heat.
A dog`s mouth carries a lot of germs, which can easily be passed to people. This is especially problematic for babies and immune suppressed adults. Both are at an increased risk of contracting infections and parasites from dogs. So, even though it may look cute, a dog licking a baby`s face should not be allowed.
Dogs have great relationships with children and are often protective of them, so it comes as no surprise that they are just as protective of babies, if not more. This is definitely a behavioral trait that needs to be looked at a bit more closely.
Hormonal treatments can be used to control reproduction in dogs, cats and ferrets. These are not generally recommended by vets because neutering brings many health benefits and the medications can cause serious side effects. However, in certain situations birth control by medication can be effective and practical.

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. What can I do to stop my dog from barking at people and front doors?
ANSWER : A. Ignore your dog’s barking for as long as it takes him to stop. This means don’t give him any attention at all while he’s barking. Your attention only rewards him for being noisy. Don’t talk to him, don’t touch him, and don’t even look at him. When he finally quiets down, 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. If he barks for an hour and you finally get so frustrated that you yell at him to be quiet, the next time he’ll probably bark for an hour and a half. Dogs learns that if they bark long enough you’ll give them attention.

Teach your dog the ‘quiet’ command. It may sound nonsensical, but 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.

When your dog starts barking, ask him to do something that’s incompatible with barking. Teach your dog to react to barking stimuli with something that inhibits him from barking, such as lying down in his bed.

Make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a good 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 fetch and playing with interactive toys.

Q. How do I determine how much my overweight pet should weigh?
ANSWER : A. There are many tools to determine overweight and obesity levels in pets. A new tool, morphometric measurements and body fat index, are available to accurately determine a pet’s ideal weight; this will allow an accurate determination of the amount of food a pet should receive to achieve weight loss. Feeding the correct amount will lead to greater weight loss success.

There are many weight loss food options to help pets reach their ideal weight. Your veterinarian can help make a ideal weight recommendation. Here are some tips to help your dog lose weight in a healthy and safe way:

1. Diet: Providing a healthy and well balanced diet is essential to your pet’s overall health. Finding the right food for your dog can be a challenging process. For those overweight animals many commercial dog companies offer weight loss diets, but it is important to evaluate food labels for adequate nutritional content.

You want to ensure you are not missing other essential vitamin or mineral content. Volume of food is also important and the amount of food that works for one breed of dog may not be the same for another breed of dog. Portion control as opposed to free-choice feeding can help your dog to drop a few unnecessary pounds.

There are also prescription weight loss foods designed by veterinary nutritionists, such as Hill’s r/d (http://bit.ly/1AoENSd). Some pet owners find that home cooking is the best option for helping to provide a well-balanced and realistic diet plan. There are websites such as balanceit.com that offers recipes to fit your dog’s specific needs. Consulting with your veterinarian or a veterinary nutritionist to find the appropriate diet is a great way to help your dog be as healthy as possible.

2. Exercise: Another great tactic for weight loss for your dog is exercise. Whether this is through running, walking or playing with a favorite toy all of these are wonderful types of exercise to help keep your dog at a lean and healthy weight.

For those pet owners with busy schedules utilizing professional dog walking services or playtime through dog daycare services is another option. It has been shown that those pet owners that exercise regularly with their pets generally live a healthier lifestyle.

3. Physical therapy: As animals age pet owners offer encounter their favorite canine having more difficulty walking and have a dwindling desire to play with toys. Physical therapy, specifically hydrotherapy is a wonderful way to help older and arthritic animals gain more mobility and lose weight. Hydrotherapy has been proven to have several therapeutic effects on the body including, muscle strengthening, relief of swelling, decreased joint pain, less stiffness in limbs, improved circulation, weight loss, and increased tissue healing to name a few.

4. Veterinary visit and blood work: Weight gain can also be related to underlying health concerns such as hypothyroidism or other endocrine disorders. Scheduling a veterinary evaluation and routine blood work can be another important component in increasing the longevity of your dog’s life. Conditions such as hypothyroidism that predispose dogs to gain weight can be treated with a daily medication to improve hormonal balance. If feel that your dog is unnecessarily overweight there can be an underlying health condition that needs to be addressed.

5. Healthy treats: Pet owners love the chance to reward their favorite canine companion with treats and most dogs jump at the chance to consume these delicious products. The problem is many treats, which can include commercial dog treats or table scrapes can add many unnecessary calories to your dog’s daily intake. Reading labels and making note of the calories in these treats is an important component of understanding your dog’s overall health. Treats should not exceed more than 10 percent of your pet’s daily calories. There are healthier treats that can be offered to your pet to keep calories lower yet provide a fuller sensation. A pet owner can add steamed or pureed vegetables, such as carrots, green beans or sweet potato to add more fiber and thus a fuller feeling for your dog.

Q. Rescued a dog almost two weeks ago, and now that her kennel cough is gone her personality shines!! No previous training, how should I start?
ANSWER : A. POST FOUR:

After your dog is familiar with the behavior you lured from scratch, and taught to your dog, you can start to use the “no-reward marker” I talked about. What you do is ask the dog to perform the behavior, and if the dog does not perform the behavior, you simply say your no-reward marker (choose one: eh-eh, hey, uh-oh, oops) show them the treat, put it behind your back, and BRIEFLY ignore your dog. Just turn your back for a second or two, before turning back to your dog and saying, “let’s try that again.” When you’re ready to start over with your dog, make sure you move around. If you are repeating the same cue while in the same position, while your dog is in the same position, you are likely to receive the same results. The more you move around, and start fresh, the better your chances are of having your dog listen to your cue the second time around. BIG rewards when they dog it successfully! Lots of praise and treats.

My no-reward marker is “hey.” When my dog does something wrong I say, “hey” and she immediately understands that she needs to offer a different behavior. This is clear to her. I don’t have to say it in a mean way, I simply say, “hey” in a normal tone of voice and she understands what the word means.

Once you’ve built up that connection and communication with your new dog, you can work on all kinds of fun behaviors! I personally enjoy the more zen-like behaviors: https://www.youtube.com/watch?v=ruy9UMcuGh8

I like to teach my dog fun tricks that offer her a “job” to do of sorts like object retrieval: https://www.youtube.com/watch?v=I4iertZSva8

(object retrieval training completed; what it looks like: https://www.youtube.com/watch?v=jx0Dml28FGY)

Scent-games are fun too! Very confidence building. Hide a REALLY smelly treat in a box, and place that box in a line of boxes. Let your dog go in the room while saying something like “search!” or “find it!” and watch them hunt for that smelly treat! Lots of rewards when they find it!

Q. My dog doesn’t eat, what should I do?
ANSWER : A. If this is a puppy, see a veterinarian immediately. Puppies should want to eat. Common causes for anorexia in puppies include viruses (parvo is a big one), parasitism, and foreign bodies. They need immediate care – go to an emergency vet if yours isn’t open. Puppies can get low blood sugar and dehydration very quickly.

If this is an adult dog and you observe other concerning signs, such as diarrhea or decreased energy, you should see a veterinarian.

If the dog seems otherwise bright and stable, try offering different types of food: wet food, canned tripe, or cooked chicken and rice. Some dogs will go for canned baby food: chicken, turkey, or beef as the main ingredient. Make sure there are no garlic or onions in the ingredients!

Causes of anorexia in adult dogs can range from less serious to severe. Younger dogs are more likely to get into trouble- they tend to eat things they shouldn’t, and can get foreign bodies from eating things like socks, or stomach upset from getting in the trash. Any dog may stop eating due to stress, or just being a picky eater. Middle aged dogs can stop eating when they’re stressed and also have Addison’s disease, which can be fatal. Older dogs tend to stop eating when they develop cancer or renal disease.

There is no one-size-fits-all recipe to know when the right time is to take your dog to the vet. The moral of this story is, if it’s not getting better, your pup feels bad, or you’re worried – go see the vet!

Q. My 4 yr old male Catahoula Leopard Dog mix is a rescue. He’s become very possessive of me around larger dogs. How can I correct this behavior?
ANSWER : A. Sudden behavior changes can sometimes indicate an underlying health issue, so scheduling a checkup with your regular vet is always the first step. Once any health issues have been addressed, then you can address the behavioral ones. It is very common for dogs to become “possessive” of people or objects when around other dogs or people, and is called location guarding. Possession of objects or places can be a little easier to manage, however possession around other dogs can be treated as well. Working from a distance in a technique called BAT or Behavioral Adjustment Training may help. This technique involves your dog and another calm dog. Start off at a far distance and then move in until your dog becomes reactive or wary of the other dog. Move back a small amount and wait for your dog to become calm. If he shows calm behavior, reward with lots of praise, treats and love! If he becomes agitated or possessive, move back until he is calm, or stop the session completely and try again later. While this may take some time, it can help dogs learn that other dogs are not a threat to them or their people. Reading more information about BAT training or contacting a local trainer in your area can help with further advice and techniques!

Q. I have a 10 year old mutt who is hyper but doesn’t like hyper dogs. Getting another dog from a shelter soon any ideas on calm breeds?
ANSWER : A. If your dog is uncomfortable with other dogs (of any sort), it is important that you bring your current dog to the shelter so he can meet the dog you plan to adopt. You should check out your local shelter, and walk around looking at all of the dogs. Mixed breeds have mixed amounts of energy and it’s tough to recommend a breed. I suppose I would say calm breeds would be the Great Pyrenees, the Newfoundland, the Bernese Mountain dog CAN be a calm breed.. really with any breed you will have mixed litters. Many breeders breed specifically the “calm” Newfies, or the “hyper” Bernese. If you are going to adopt from a shelter however, it’s impossible to expect that level of breeding.

As I said, just be sure you bring your dog along so you can slowly introduce the dogs. If your dog is uncomfortable, immediately separate them, and try again in a couple of minutes. You don’t want to force them to get along, and you don’t want to move too quickly when introducing them.

Q. My Beagle listens to me, but cries & whines when I’m gone & doesn’t listen to my parents. I adopted him just a couple days ago. Any tips for my folks?
ANSWER : A. I really highly doubt that your Beagle listens to you and has formed a connection with you in just a couple of days. It takes months to build up any kind of serious connection with your dog. You need to work on communication with your dog through training them to understand different cues. For instance the Leave-It cue: https://www.youtube.com/watch?v=R1TS5nA7z5Q

You have to work on bonding with your dog through mental stimulation. Training is very important. Luring each new behavior from scratch, and training using treats is how you form a strong bond with your new dog. No scolding is ever necessary… work on being calm, and positive, all the time.

If your dog is crying/whining when you leave, this may be separation anxiety. You’re going to have to separation train this dog from scratch. This dog needs to learn that separation can be a good thing! Tell your “folks” to NOT scold the dog when he is crying/whining after you leave, because that will make your dog MORE anxious when you leave next time. Your dog will be dwelling on the negative if your parents fuel your dogs negative feelings towards you leaving. FUN things should happen when you leave. Your parents should pull out the treats and start doing some basic obedience training with your dog. Your parents should stuff a Kong filled with awesome treats (peanut butter) and give it to him so he feels happy when you leave.

I have some excellent separation anxiety exercises you can work on. If you’d like, you can purchase a consultation with me, and I will go over how to separation train from scratch. It will make your dog comfortable being alone, guaranteed.
