A. It depends how long it sits in his stomach for (this can vary greatly). I would expect it to be passed within 2-3 days. If he starts to vomit, strains to pass faeces, off food or lethargic then you should see your vet straight away as it may cause a blockage.

How to Identify Common Pet Problems ?

Our dog`s stomach acid will not dissolve plastic, not even soft ones. If your pup eats a plastic spoon, plastic bag, or another item, it will have to leave his body. He will have to vomit it up very soon after eating it. After two hours, he will have to eliminate it with his feces.
It generally takes ingesta (all that is swallowed) from 10-24 hours to move through the entire digestive tract. Some objects, however, can actually remain in the stomach for longer periods of time, even months.
Even swallowing just a little bit of plastic can cause a deadly bowel obstruction, so it`s vitally important to respond as quickly as possible by taking your pet to the emergency vet if you suspect or know he has swallowed plastic.
If you know your dog swallowed an object, call your veterinarian immediately and take your dog to the vet`s office as soon as possible. The doctor may be able to induce vomiting or retrieve the object from the stomach before serious problems set in.
Given the right conditions, such as heat, microbes, moisture, and oxygen, dog poop will decompose within two months and a week.
If your dog has eaten plastic or something else they shouldn`t have, feeding a bulky meal to try to pad out any sharp edges and help it to pass can be a good option. Asparagus is often used for this.
Diarrhea/difficulty defecating (pooping)/Straining to defecate: A dog with a partial blockage may have diarrhea as liquid squeezes around the obstruction. If there is a complete blockage, the dog may try to defecate but won`t be able to.
Ask your vet if it`s okay to feed a bulky meal of dry food or a slice of plain bread. This may cushion stones or other heavy objects and help them move on out. Food also activates digestive juices, which can help soften wads of rawhide so they pass more readily.
Bread binds or pads swallowed foreign objects like sharp bits of bone – or indigestible objects – enabling them to pass through the digestive tract. This is not true for all foreign objects or shards of bone, but bread can help your dog digest small pieces.
Dogs can safely eat bread in much the same way as humans—in moderation. Plain white and wheat bread are generally safe for dogs to eat, provided they don`t have any allergies, and it usually does not cause any stomach upset.
Some foods, such as onions and garlic, as well as beverages that are perfectly safe for people can be dangerous, and sometimes fatal, for dogs. Alcohol. Symptoms of alcohol poisoning in animals are similar to those in people, and may include vomiting, breathing problems, coma and, in severe cases, death.
Your dog will likely pass the rock they ate in anywhere from 8 to 24 hours, depending on how large it is. However, dogs can`t pass it without some pain. Eating rocks can also cause intestinal blockage if the rock is too large to pass through the intestines.
WHEN YOUR DOG GOES ON THE LAWN, REMEMBER IT DOESN`T JUST GO ON THE LAWN. Rain washes dog poop and its bacteria into storm drains. From there, it goes on to pollute our waterways.
Parasites, bacteria, and other germs can spread through pet poop. Always wash your hands after scooping litterboxes or picking up dog poop, even if you used gloves or a bag.
One of the most common causes of white poop is a diet that is high in calcium, which causes a change in the color of the poop. Dogs that consume a lot of bones will often have white poop. Most of the time, white poop caused by too much calcium isn`t too concerning for dogs, but too much calcium may cause constipation.
Without appropriate and timely treatment, dogs with a complete intestinal blockage will typically see fatal complications within 3-4 days. Given time, some foreign objects can pass on their own.
Most dogs with a GI obstruction have severe abdominal pain as well as a lack of appetite. A classic sign of pain is the bowing down position. Your dog may not want to be touched on the tummy. Or she may groan and be tense and wide eyed when you touch her there.
You`ll want to watch your dog`s stool for several days (at least 72 hours) after they eat the bone for signs of bone fragments. In addition, you should still follow up with your vet in case there`s any remaining bone left in your dog`s intestines or esophagus. The bones can splinter and puncture these internal organs.
A pet with a urinary obstruction is unable to urinate normally. Urinary obstructions may be partial or complete, and the signs you may notice at home can range from subtle signs like taking longer than normal to urinate or urinating small amounts in several spots to severe signs such as collapse.
Unless you have seen your dog swallow a foreign object, symptoms of dog intestinal blockage are usually dismissed as an upset stomach. Symptoms include the following: Vomiting. Loss of appetite.
An object caught in the stomach or intestines causes vomiting, which may come and go for days or weeks if the blockage is not complete and food can pass around it. A complete blockage is a medical emergency that results in a bloated, painful stomach with sudden, constant vomiting.
It is recommended to be finished breeding when your dog reaches the ages of five to seven. After this age, dog pregnancies are rather difficult on animal`s bodies. Dogs are at a significantly greater risk of having miscarriages, being injured, or even dying during pregnancy after a certain age.
According to Dr. Diehl, if a dog ate a sock, many dogs, especially large dogs, will either throw up socks or pass them in their stool. If your dog is not acting sick and isn`t throwing up, one option is to wait and see if it comes out on its own.
In the prayer position, the dog stretches far forward with the torso almost resting on the ground. The front paws are stretched out and also rest on the ground. Unlike the low lying torso, the hind legs are stretched wide and steeply upwards. The hind legs are therefore fully extended.

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. 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 is house trained but has started pooping in the house, why is she doing that?
ANSWER : A. It could be the type of food you are feeding. If you are feeding a lower quality kibble, it will be packed with fillers. These fillers will cause your dog to poop more than is necessary, and it can cause your dog to poop indoors because of the excess poop. Finding a higher quality kibble like Taste of the Wild, Orijen, or a high quality food like Ziwipeak, or Honest Kitchen, will help with that issue.

Remember to NEVER scold for accident indoors. The more you scold, the more fearful your dog is of pooping in front of you, the less your dog will want to poop in front of you outdoors, the more he will poop indoors, the more you scold… it’s a vicious cycle.

Have you been cleaning messes with Nature Miracle? Pick up a bottle, and try cleaning with that instead of regular cleaner. It will eliminate the smells deep down (even to your dog), which will discourage him from potting in that spot again.

Maybe he needs to be taken outside more often, and maybe he needs to be kept outside longer each time. He should be allowed at least 10 minutes of roaming outside before he has to come back inside. Allow him 10 minutes every single time you bring him outside, just in case he has to poop. He needs every opportunity you can give him. Bring him outside every hour if he’s full grown, every 40 minutes if he’s an adolescent (6-10 months), and every 30 minutes if he’s a puppy (2-6 months). If you have a doggy door, you should still be bringing your dog outside yourself to encourage him to stay outside longer, and poop. When he does poop outside, you should praise him, and reward him with lots of treats!

Q. How long would it take a big dog, his back is about 23 in. Tall, to poop out a 1/4in. x 3in. Casing from liverwurst that he ate last Sunday?
ANSWER : A. It depends how long it sits in his stomach for (this can vary greatly). I would expect it to be passed within 2-3 days. If he starts to vomit, strains to pass faeces, off food or lethargic then you should see your vet straight away as it may cause a blockage.

Q. Husband shamed dog for having an accident inside, and now she won’t poop when he takes her out. Can we fix this? He realizes he erred
ANSWER : A. Good on your husband for realizing that scolding is not the way to potty train! Hopefully these tips can help both him and your pup get back on the right track and make pottying outside successful.

If your dog is still a puppy, that is good news as you may be able to more easily time your potty outings with your dog’s schedule. Even if your dog is older, this schedule may help. Dogs generally have to go potty about 15 minutes after eating, drinking, waking up or playing. Knowing this, get your husband to start taking out your puppy at these key times, so puppy gets used to going out with him, and the urge to potty may be higher than any fear to go. If the potty is successful, have your husband reward the dog with a favorite treat! For bowel movements, dogs may take a little more time, and you may have to stand outside for a while (sometimes even 10 minutes) to give your dog a chance to go. If she doesn’t go, take her back inside and play some, then try again in about 15 minutes. Again, a success equals a treat which most dogs will like right away!

For any indoor potty accidents that occurred, an enzymatic cleaner is great for cleaning up urine and stool. Not only does it remove the stain and smell, but it breaks down the enzymes in the urine and stool your dog can smell, which may deter her from going potty there again.

Q. Why does my dog eat grass?
ANSWER : A. As another user mentioned, dogs can eat grass when they want to vomit. Sometimes, when a dog has an upset tummy, they will eat grass. If you notice your dog eating grass frantically, you can assume vomiting will shortly follow. Grass does not digest and pass normally. If your dog eats too much grass, it can cause serious issues with pooping. Your dogs poop can end up all tangled inside of her, and it can need veterinary assistance to remove it. The same goes for celery, so avoid feeding celery to your dog.

The other day my boyfriend accidentally left the laundry room door open where we were keeping the trash that was filled with cooked chicken bones. She ate one of the chicken bones lightning fast. We had to induce vomiting by feeding her some hydrogen peroxide. After we had fed her the peroxide, she immediately began frantically eating grass because her tummy was upset.

If there is something lacking in your dogs diet, it could be that your dog is eating grass to make up for it. I am sure that my dogs diet is extremely well balanced (I do not only feed her an air-dried raw food-type diet (Ziwipeak), but a wide variety of safe, healthy foods), so when she eats grass, I know that it is because she has an upset tummy.

That is why I think it is important making sure your dog has a very well balanced diet. If your dog is on a low quality kibble, your dog may be trying to let you know by eating grass (or eating poop).

Q. How do I desensitize my dog to squirrels and stray cats in the neighborhood?
ANSWER : A. It depends on the goal that you have in mind. I am going to assume that you would prefer that your dog not chase squirrels or stray cats in the yard/street. In this case, your options include: (1) training your dog on a “Leave it ” cue using positive reinforcement methods, (2) training your dog not to pull on its leash when it sees a squirrel/stray cat, and (3) training your dog to perform a more desirable behavior when it sees a squirrel/cat.
Training your dog on a cued “leave it” command is useful because it will give you the ability to tell your dog to stay away from any number of undesirable objects on your command. Training your dog to perform a more desireable behavior when it sees a squirrel or cat will substitute a behavior you find acceptable (sitting, laying down, coming to the door, etc.) with a behavior you dislike. Your dog can still react, just in a positive way. If your dog pulls on the leash every time you see a squirrel/cat, training not to pull will make your walk safer and more pleasant.
The ideal training method to use with dogs, or any animal for that matter, is positive reinforcement training, particularly a method called “clicker- training.” The basic concept of positive reinforcement training is to pair a reward (reinforcement) with a behavior you want to increase in frequency. In other words, when your dog performs the behavior you desire, it receives an award, which reinforces the desired behavior so you get more of that behavior. There are many excellent books in stores or on-line that describe positive reinforcement training in detail and many give step-by-step instructions for training common commands like “leave it”. Look for books that specifically mention positive reinforcement training or clicker-training. You can also take dog training classes to learn the techniques, find a mentor who already uses clicker-training, or request a consult from one of the pet experts on this site to guide you.
