How to Identify Common Pet Problems ?

For your first introduction, find a space in the centre of the room where the puppy doesn`t feel cornered and where they feel they can easily escape if they feel they need to. Get your child to calmly approach from the side, then allow your puppy to come the rest of the way.
Positive reinforcement is one of the best ways in which you can train your dog to behave better around kids. Encourage good behavior from your pet with attention, praise, and treats. Your dog will start associating your kid(s) with good things if you do this often enough.
At first, walk the dogs at a distance where they can see each other but are not too provoked by each other`s presence. If the dogs are not showing any negative behaviors, reward them with treats just for seeing each other.
The general rule for the safety of both the child and the puppy is for them to always be supervised when together. And kids should learn that puppies are living creatures, not toys. After the puppy is taught to respect the puppy and his area, they can be together when observed.
A simple test you can try is to remove the child from the situation and then see if the dog comes back to the child for more attention. This will tell you if the dog was enjoying the interaction (comes back for more), or just tolerating it (stays away, or leaves the scene).
If your puppy starts to get mouthy or jump on the kids, intervene by calling the puppy`s name (in a very high pitched sing-songy voice) or clapping. Once you`ve got her attention, redirect her onto toys and food puzzle toys, something appropriate that will hold her attention.
There are some things we can do to help them settle and feel safe in those first few days. Keep in mind though, that it generally takes about three weeks for a dog or puppy to start to feel `at home` and to show their true nature.
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. If you want a second dog, you need to be ready to commit to this process and not panic.
The most challenging time of raising a puppy is the adolescent period. Dogs become “teenagers” and seem to forget everything they have ever been taught. This period is individual to each dog, but it may begin when he`s about eight months old and continue until he`s two years old.
Puppy difficulty at ages 7-10 months

It can vary a bit based on each dog, but your puppy likely will hit “adolescence” around 7-10 months, with 8-9 months being the peak described by most owners.

Dogs are gentle with children, and they can form strong bonds with them due to the time they spend together. If you think about it deeply, both a puppy and a baby share the common interest of playing and exploring their surroundings. If your dog and your child have grown up together, their bond is inseparable.
Recent studies by animal psychologists have confirmed that dogs do in fact experience jealousy when their owners display affection toward other animals, new partners, kids, or even inanimate objects.
The age of your children is one factor to consider when getting a pet. Generally, since many dog bite injuries happen to young children, it may be safest to wait until your child is older than age 4. But think about your children and their individual maturity levels, because each child develops differently.
Reasons Why Your Dog Might Not Like Kids

There`s a chance it`s because of: A lack of socialization: If your dog didn`t experience enjoyable interactions with children during the puppy socialization period, they might seem scary or overwhelming to him.

If your dog growls at your child he is sending a clear warning that he is very uncomfortable with the actions or proximity of the child. Be grateful that your dog chose to warn with a growl rather than going straight to a bite.
Many dogs think children are the best toys and playmates in the world. If your dog is gentle, this can be a wonderful thing. Unfortunately, some dogs, especially those who have had no obedience training, rules or guidance in their lives, happily mouth or jump up on every child they see.
The instant you feel your puppy`s teeth touch you, give a high-pitched yelp. Then immediately walk away from him. Ignore him for 30 to 60 seconds. If your puppy follows you or continues to bite and nip at you, leave the room for 30 to 60 seconds.
They are OVEREXCITED. Young puppies have not yet learned to regulate their emotional arousal. When then become overly excited or aroused, they start to lose inhibition and self-control, which leads to them getting extra bitey.
Simply reward your dog with wonderful things like treats, toys, and games when children are around. For example, if a child comes up to your dog on a walk, feed your dog treats while the child pets them. In no time, your dog will look forward to encountering kids while you`re out on the town.
First thing first, calmly SEPARATE the dog and the child. Either by calling the dog to you or by calmly removing your child. Don`t be tempted to try to lift or physically move your dog or you could risk a bite yourself. Secondly, DON`T PUNISH THE DOG for growling.
The amount of time each individual pet needs to adjust to their new homes will vary, but the 3-3-3 rule helps give an approximation of what new pet owners can expect. The 3-3-3 rule refers to the first 3 days, the first 3 weeks, and the first 3 months after bringing a shelter animal home.
While it is completely possible for dogs to love new additions to the family, it is important to remember that dogs are sensitive, in tune, creatures that have the capability of feeling upset, jealous, or unloved just as us humans do. While life can be a whirlwind, it is important to take a time and smell the roses.
Puppies can learn their names quickly (most can pick it up within 1-3 days!) but generally, you`ll want to practice using their name regularly. A good way to start teaching your puppy their name is to use it to gain their attention by saying their name and rewarding them when they look at you!.
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.

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. My puppy is urinating a lot. And the lady I gave one of the puppies to said she thinks her puppy has diabetes could my puppy have it to
ANSWER : A. It is not likely that either one of these puppies has diabetes. It is very uncommon for a puppy that young to have diabetes. If your puppy is straining to urinate or is urinating very small amounts frequently and cannot seem to wait for very long between urination, he may have a urinary tract infection. It is quite possible that your puppy is completely normal. I would suggest an exam with your veterinarian and discuss the behavior with them. They may suggest a urinalysis. Your puppy should be going to the vet at 3 week intervals for vaccinations at this age, so you can discuss it when he has his next set of vaccines. The other person with the other puppy should also be taking hers to a vet for proper immunizations and she should also discuss her concerns with her vet.

Q. What’s the best way to introduce my puppy to a household with children?
ANSWER : A. Talk to your kids about the responsibilities and precautions they will need to learn to take care of a puppy. Children must be taught that a puppy needs to be handled gently and has to be given time to adjust to its new home.

Q. My Shih Tzu had puppies 6 weeks ago. What complete dog food is reccomended to harden stools?
ANSWER : A. If your Shih Tzu is still nursing her puppies it is best to feed her a puppy or nursing formulation. This will help her to make enough milk so that the puppies can continue to grow big and strong! If she is having loose stools, adding in some pumpkin puree to her diet can safely add fiber to bulk up stools some without affecting the puppies. However, if the loose stool continues for a while, scheduling a checkup with your local vet is always best. Have fun with the puppies!

Q. What solid food should I start 4 week old Pit Bull puppies on?
ANSWER : A. A puppy food designed for large breed puppies can help with rapidly growing bones and joints and can be given in a wet form easily to puppies learning to eat solids. You can also provide a dry kibble for them to try and should moisten it with water or some formula to make it easier for the puppies to eat and digest. As the puppies grow and their teeth come in, they will begin to eat and explore more of the solid food on their own.

Mom should also be on a Puppy formula while nursing her puppies as it will provide extra nutrients to both her and babies while they are in a very rapid stage of growth!

Q. How should I discipline my puppy when an “accident” occurs?
ANSWER : A. The puppy must be disciplined as soon as the mistake has been made, when the incident is still fresh. Reprimands made for accidents that happened some time ago are futile at best, and harmful if done improperly. If you catch the puppy as he is making the mess, or is about to make a mess, discipline him in a firm way without being too severe by using startle techniques that will cause him to immediately stop what he is doing. A strongly voiced “No” or “Stop”, a sudden loud noise to catch his attention, or taking hold of the scruff of the neck are all good ways of turning the puppy’s attention from what he is doing and toward you.

Follow all of these actions by immediately taking the puppy outside to finish relieving himself and reinforce the “good” behavior (going outside) with rewards such as patting, verbal praise, and/or training treats.

Q. How long should I feed puppy food to my puppy?
ANSWER : A. A puppy should be given puppy food from around the time that the mother begins weaning her pups until the puppy reaches about the age of one year. This is generally true for all dogs, unless your veterinarian has concerns about your puppy’s growth. Under those circumstances, your veterinarian will make alternate recommendations for your puppy’s diet. Otherwise, around one year, you may begin giving your puppy an adult formula dog food at meal times.

Q. I have 2 puppies that I think may have parvo, the little one is throwing up thick bubbly puke and watery stool. Can the vaccinated mom still get sick?
ANSWER : A. If you suspect one or both of your puppies have parvo, it is best to bring them into a vet for care. Parvo is a very serious and contagious disease and it can kill puppies without proper treatment.

As Parvo IS very contagious, it is best to keep the sick puppy isolated from any other dogs in the house. While your adult dog is less likely to get ill due to vaccination, no vaccine is 100%. Your other puppies if not vaccinated are also very likely to get ill. Be sure to thoroughly clean any surfaces your sick dog comes into contact with as Parvo can live in the environment for up to several months if not properly cleaned.

If your puppy is very ill, your vet can run a fecal test to look for Parvo. Parvo symptoms usually include vomiting and diarrhea that often is blood-tinged. Parvo can cause dogs to become very dehydrated and unable to keep food, liquids or medications down and usually require hospitalization and IV fluids to provide medications and nutrition while they are ill.
