How to Identify Common Pet Problems ?

Puppies should be at least 10-12 weeks old before they`re ready to start socializing and going outside in public places. This allows them time to get all of their vaccinations and build up their immune system so that they`re not as susceptible to illness from another animal or person.
You might find puppy training is far easier with an older dog and a new pup—the puppy will look to his senior for guidance, and model his behavior after hers. Having an older dog can make potty training your puppy way easier, too.
While the majority of dogs will get along well with their new sibling, your first dog may not be happy having to share their toys, space, territory, or even their owner`s affection. This makes it important to prepare and do your research when getting ready to bring home a second dog.
Dogs are social animals and usually happier around other dogs, but a second dog will never be a substitute for inattentive, absent or too busy owners.
You can start walking your puppy after one to two weeks of them being fully vaccinated. This is usually around the 8-week mark. However, make sure you keep a strict eye on them and ask your vet to confirm when they`re allowed out on a walk.
Introduce on neutral territory.

Each dog should be walked separately on a leash, and each walker should have a bag of high-value treats or food broken into small pieces. At first, walk the dogs at a distance where they can see each other but are not too provoked by each other`s presence.

In dogdom, there`s a turn of phrase called, “Second Dog Syndrome”. This describes the process of adding another dog to the home quite well, but not necessarily in a positive light. As humans, we are bound to forget all of the time and effort it takes to raise a puppy right.
Before settling on a breed, think about the gender of the dog. For the happiest dogs and the safest household, opposite sex dogs almost always do best together. Many same-sex combinations of dogs will fight, sometimes to the death. Those who work out a dominance order may not fare much better.
And when the house`s vibe feels off-kilter, some guilty feelings can creep in. “I believe dogs have a rich emotional life, and they feel very connected to their people,” Plymale says. “So there can be friction (for everyone) when a new dog comes into the picture and the dynamic of the house changes.
“For 95 to 98 percent of dogs, the simple answer is yes, they like having doggy buddies,” says Nicholas Dodman, BVMS, professor emeritus at Cummings School of Veterinary Medicine at Tufts University and a board-certified veterinary behaviorist. “But not every dog wants a doggy buddy and that`s okay.”
Training is Easier with Two Dogs

Puppies often learn from older dogs. This means that they learn tasks like potty training and basic commands much faster when they have an older dog to model themselves after.

However, many experts agree that the best time to socialize a dog is before they reach six months old. This is because puppies are more open to new experiences and learning during this stage of their lives. After six months, dogs can still be socialized, but it may take more effort and patience on your part.
Puppies less than 12 weeks of age that react to pain or fear by growling or snapping are responding abnormally. Puppies in a dog pack would be attacked if they responded aggressively to correction by an adult dog. It isn`t normal brain development for a puppy to do that to people or other dogs.
On the first night, and for about three weeks, have the puppy sleep in a dog crate next to the bed.
Vets suggest that puppies should only be allowed on the stairs after the age of 12 weeks – and even then, they should be closely supervised. With some large breeds, such as Labradors and Retrievers, it`s advisable to wait even longer.
Caring for a second dog will take more time and money: You`ll need to feed them. They`ll require veterinary care, walks, supplies, and maybe boarding. Or, if you travel with your pups, you`ll have to manage the logistics of bringing a second one with you.
Make sure your lifestyle is prepared to welcome a new energetic pet. If you look forward to the new life you can give a dog and feel ready to move forward then you might be ready to start looking for your new pet. When you begin to look for your new furry friend don`t get discouraged if you don`t them right away.
You`ll need to wait until your puppy is fully covered by their vaccines before they can meet most other dogs. By waiting, you will help to reduce the risk of them getting the nasty diseases that vaccines protect against.
Many people do not give two dogs time to adequately adjust to one another before deciding that having two dogs will simply not work. It can take up to one month for an old dog and new dog to really settle in and accept each other`s position in the pack.
What exactly is “littermate syndrome” and is it real? Littermate syndrome can occur when two puppies adopted from the same litter grow up together in the same home. In some cases, these sibling puppies form such a deep bond with each other that they fail to properly socialize with people and other dogs.
Bringing home a new puppy or another adult dog can trigger jealousy in your dog, and they may show signs of aggression toward the new addition. Your dog might growl at the new dog, guard your lap, or try to get in between you and your new furry family member.
Happy tail syndrome in dogs occurs when this strong tail repeatedly hits solid objects with force during a wagging session, resulting in the thin skin of the tail splitting open. You would think that this injury would be enough to stop even the happiest tail in its tracks, but alas this is not usually the end of it.
Benefits of getting a second dog

You can double the fun and silly antics in your home. your first dog`s anxiety. Younger dogs can become playmates for each other. entertain each other instead.

So, if you get a 2nd dog, please make sure and socialize them on their own. Walk them on their own, take them to new places alone, and especially take them to the dog park without your other dog so they can be taught appropriate behavior by new dogs and not just rely on interactions with their sibling.

the most relevant questions and answers related to your specific issue

Q. How do I get my dog to stop chewing on things? I kennel her when I leave for a few hours, but I can’t go to the mailbox without her eating something.
ANSWER : A. If she’s young, then this is just normal puppy behavior. Don’t worry about it. The thing about puppies is, they explore using their mouths. If your puppy grabs a coat hanger, or a slipper, you should roll up a newspaper, and smack yourself on the head with it for leaving those things out.. your puppy is going to explore things, that’s normal! It is 100% up to YOU to keep those things away from your puppy when your puppy is unsupervised… even for just a moment.

Remember to never scold your puppy for grabbing these things. They are just curious little cuties, and they don’t chew things up to bother us.. Dogs do not have intentional thought, so they aren’t ever doing anything ON PURPOSE to us.. The most important thing you can do when your puppy is chewing something you don’t want her to be chewing is TRADE her the inappropriate item with a toy of hers, so she understands “no honey, that isn’t what puppies chew on… THIS is what puppies chew on!” and then begin playing with her using her toy to show her that TOYS ARE FUN.. Way more fun than a boring ol’ coat hanger.

Another helpful thing you can do is have two bags of toys. In each bag is many different kinds of toys. Lots of chew toys, lots of soft squeaky toys, lots of rope-type toys, a bunch of balls.. All kinds of things! For one week you have bag#1’s toys out for your puppy to play with.. At the end of the one week, you collect those toys, and you bring out bag#2! The toys will be more interesting/feel like new to your puppy, which will in-turn, make her chew less inappropriate things. Her toys are too fun to care about that dumb Wii-mote that you left laying around.

Hope this helps!

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.

Q. My Bulldog puppy growls, barks and even tries to bite me when I say “no” to him. What can I do?
ANSWER : A. First, avoid scolding him and acting aggressively towards him if you don’t want him to be acting aggressively towards you. There are other methods you can use to communicate to your dog that you don’t want him to continue doing what he is doing. I recommend you stop telling him “no”, scolding him, or raising your voice at him. Everything coming from you should be 100% positive and 100% calm.

Try to figure out ways to clearly communicate what you want to your dog. If you want your dog to leave something or someone alone, I strongly suggest teaching your dog commands like “leave it”. Here is a link to a video in which I explain how to do it:

www.youtube.com/watch?v=R1TS5nA7z5Q

Another thing I suggest you use is a no-reward marker. This clearly communicates when your dog has done something wrong. No-reward markers have to be introduced during your training sessions. You should be doing at least three training sessions per day, that are something like 3-10 minutes long (working on different things each training session). If you are teaching your dog something BRAND NEW, do not use the no-reward marker, as you do not want to discourage your dog from performing behaviors for you. Use the no-reward marker for known behaviors only. Here is another helpful video about this:

www.youtube.com/watch?v=sdU5a6fXKlg

Lure each new behavior (as shown in the video) using high value treats. Let’s say you’re working on “down” which is a behavior your dog knows fairly well. Present the treat to your dog. Ask your dog to “down” (only ask once). If he does not go “down” immediately, say, “uh-oh” or “eh-eh” in a gentle tone, and then place the treat behind your back. This communicates to your dog that they did something to make the treat go away.

After you place the treat behind your back to show your pup “that was wrong” you need to communicate to your pup “let’s try again” by getting your pup to walk around for a second, and then start the behavior all over again. If your puppy is very young, chances are you haven’t taught him a solid “down” behavior yet. So, as I said, do not use this method until you have lured each new behavior as shown in the video.

This is the order in which you should teach behaviors: Lure using a high value treat as shown in the video. After a few successful food lures, lure with an empty hand. If the pup is successful with the empty hand lure, reward with lots of treats. If the pup is unsuccessful, then go back to food-luring a couple more times. After a few successful empty-hand lures, you can begin to add the cue. Say “sit”, then lure with an empty hand, and then reward. Once your pup understands the cue, begin to work on the no-reward marker.

Q. I want to get another puppy so it can grow up with my new puppy of 8 weeks, is this a good idea or will it make it harder to train them?
ANSWER : A. It will definitely harder to try 2 puppies, but there are also a lot of advantages, they will play a lot together and won’t be bored when you’r not around.

Q. My 3 month puppy eats his own poop and is also biting what can I do to prevent this
ANSWER : A. When it comes to poop eating, you want to consider a few things. First off, what is his diet like? Maybe something is lacking in his diet that is causing him to want to eat his own poop. This is the most common reason why dogs eat THEIR OWN poop. Try a higher quality kibble like Taste of the Wild, Ziwipeak, Orijen.. and try feeding three meals per day, instead of the more common two meals per day. Remember to gradually switch his kibble. Add a little bit of the new kibble and reduce the old kibble very slowly.. little by little every couple of days until the bowl is mostly new kibble! You should also be cleaning up his poops IMMEDIATELY after he does them.. I mean like, you have a bag in your hand, and you are low enough to scoop it up RIGHT when he finished so he doesn’t have a chance to eat his poop.

When it comes to nipping there are a few things you can do. First, you should yelp as soon as the teeth touch your skin, stand up, cross your arms, and ignore the puppy until he is ignoring you. Once he is off doing his own thing, swoop down and calmly reward him by playing with him WITH A TOY so he doesn’t nip your hands. Whenever you pet him, or interact with him, you should always have a toy on-hand so you can give it to him. This toy should be a soft braided rope toy that YOU own. This means, your puppy is never allowed to have this toy on the floor, and your pup can never “win” tug games with this toy. This is YOUR toy that disappears when you’re finished playing, and reappears when you want to play. If you keep this up, in a weeks time, your puppy will be so excited to see that toy, that as soon as you bring it out, he stops nipping you because he wants to play with the toy. Another thing you can do is have two bags of toys. Bag#1 is full of chew toys/soft toys/squeaky toys/etc. After one week, Bag#1 disappears and out comes Bag#2. Bag#2 has the same types of toys as Bag#1, and it only stays out for one week. This keeps the toys feeling like new to your pup!

Q. ALL ABOUT EYE CONTACT.. MY FEMALE ESS, UPON GETTING EYE CONTACT FROM PEOPLE SHE CRIES, WHINES & WANTS TO JUMP FOR ALL THE ATTENTION SHE CAN GET..
ANSWER : A. Somewhere along the line she has learned that this gets her something she wants, attention, food, something, and now we have to teach her that behaving and being quiet gets her what she wants. Don’t reward her whining and bouncing by giving her attention. Instead, ignore her, going about your business until she quiets and settles down. THEN give her a treat, petting, and praise. She needs to learn that being the well-behaved dog is what will get her the attention she craves. Teaching her obedience will help her learn how to behave in various situations and to look to you for how to behave. And, above all, 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 and misbehave from boredom or frustration. Depending on 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. Kong toys filled with peanut butter are an excellent way to reward her for being quiet and keep her that way for a good while as she plays with her toy and gets the peanut butter out.

Q. What is the best way to train your dog on a pee pad? He can go on the pee pad if I bring him to the pad if I don’t he makes an accident.
ANSWER : A. Train your dog using a positive reinforcement method. Since your dog will use the pad when you bring it to him, reward him immediately for urinating on the pad. First, teach your dog to associate the word “good” with a treat (or use a special device called a “clicker” in place of a verbal “good”). Then, say “good” or “click” when you dog urinates on the pee pad and reward him as soon as he finishes. Repeat this training over and over until your dog understands that peeing on the pad equals reward. Then, begin to move the pad away from your dog and bring him to the pad wherever it is. Again, reward when he goes on the pad. It is all about making it “fun” to pee on the pad (reward) and not fun to pee anywhere else (no reward). To learn more about “clicker training” and/or positive reinforcement training, I recommend purchasing a good book on training using positive reinforcement techniques. Or, I or another of the experts on this site, would be happy to consult with you to guide you through the steps and make this a positive experience for both you and your dog.

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.
