How to Identify Common Pet Problems ?

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

Depending on how much time siblings spent together before getting separated, it`s possible for them to remember each other`s scent. This is not the same as a conscious awareness of their shared lineage, but functionally it does mean that dogs could be able to remember their siblings.
On most occasions, it is generally considered dangerous to breed brother and sister dogs together. This is because of the risk of long-term health complications. Even if inbreeding is carefully planned and managed, it still has the potential to cause other indirect problems over time.
One study used scent-based tests to determine whether dogs recognized their mother and siblings two years after leaving the litter by the age of 12 weeks. They found that by the age of 2, dogs could only recognize a sibling they lived with—not any of their other siblings.
So in short – yes, puppies miss their siblings at first. But they quickly get over it. Dogs don`t really have the mental capacity to reflect on their early-life peers, so they won`t really “miss” their siblings in the way a human might.
As mentioned in our “Picking a Puppy” article, littermate syndrome is a serious behavioral condition. The condition develops when two young dogs end up bonding too tightly with each other. It may sound ideal when dogs are such close friends, but major issues can arise down the road.
The results of these two experiments clearly show that young puppies recognize their own mother and littermates, and it also shows that this recognition is based upon scent cues.
As a general accord, it is often highly advised NOT to breed father and daughter dogs because of the number of risks associated with it. In fact, this type of breeding has been banned by The Kennel Club.
Inbreeding occurs when puppies are produced from two related dogs, i.e. dogs with relatives in common. High levels of inbreeding can affect the health of these puppies, although it is difficult to know the exact impact it can have.
A dog`s memory has been the center of many studies over the years and studies have shown that they can remember their old friends, but to them, they have no idea that it has been long at all since they last saw their friend.
As you can see, while your pup may not remember specific events from puppy phases, there are experiences of care and interaction that condition your pup with skills that they will take into dog maturity.
They have the same feeling as a child towards their parents and so they are not just an animal but a child to us and for them we are family. If ever you wonder whether your pooch is just like your child or not, think again. For them you are their parents.
This is different for every dog and entirely dependent on their personality and training. For some dogs, it can take 6-8 months, for others it`s 12. When you leave the house for long periods of time, you should make sure your pup has access to their bed, some drinking water, and preferably, some toys.
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.
Signs of littermate syndrome include fearfulness of unfamiliar people, dogs, and other novel stimuli (neophobia); intense anxiety when separated, even briefly; and difficulty learning basic obedience skills. In some cases, the two dogs will fight incessantly.
Littermate syndrome is an unscientific term that describes unwanted behaviors among sibling dogs, including aggression and intense attachment. The phrase is often used to describe behavioral issues that occur when two or more dogs from the same litter are raised together and adopted into the same home.
Your dog might jump on you, lick your face, and they`ll definitely wag their tail. Being excited and happy to see you is one way you can be assured they love and miss you. They seek physical contact. This can come in the form of a quick nuzzle, a cuddle, or the famous lean.
After your pups have reached the appropriate age, you will become their “parent.” If the canine mother is no longer in the home, it is natural for a puppy to cry or whine at first as he adjusts. When the puppy is first separated from his mom, he will need a lot of attention and contact from you.
​The highest level of inbreeding by far (> 80%) is for the Norwegian Lundehund. This breed suffers from extremely low fertility and high puppy mortality as well as an often lethal gastrointestinal disorder.
Gender and the impact of breeding also come into play. Female dogs live longer than males by an average of one and a half years. If a dog is extensively inbred, it will likely have a shorter life.
Inbreeding not only results in reduced litter size, but it also leaves inbred pups smaller than non-inbred dogs of the same breed. In some cases, inbred dogs have asymmetrical features, ranging from eyes of different sizes to misaligned jaws.
Inbreeding depression is the reduced survival and fertility of offspring of related individuals. Large effects are documented in wild animal and plant populations, as well as in humans. Intercrossing inbred strains improves yield (heterosis).
Offspring from a mother-son mating would, therefore, have a 25% chance of inheriting two bad copies of the mutations that have been passed down to the son. This is a greater than 100-fold risk compared to an outbred dog! Inbreeding in dogs has real consequences.
You need to keep the original sire and dam, too. Breed three generations of female puppies back to your original sire. This concentrates the blood. This is called line breeding since you are breeding in a line back to the original sire.
According to Dr. Brian Hare, a canine cognition specialist, our dogs do know we love them. Dogs and humans have the ability to form a special neural connection. This connection is the same human oxytocin bonding pathway used by parents and babies.

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. 1 wo. puppy born smaller than the rest, so is not able to drink from mom. Very tiny, unable to gain weight and cries a lot…
ANSWER : A. There is usually a “runt” puppy of the litter that tends to be smaller than the rest, usually because he cannot or does not get enough milk from mom. Be sure to read the amount to feed on the formula you are using as young puppies will need to be fed a lot several times a day (and night) to allow for their rapid growth. However, if you are bottle feeding the puppy and he is still not gaining weight compared to the other puppies, he may be experiencing a failure to thrive. This can be caused by a number of things ranging from problems with anatomy (such as a cleft palate or opening in the top of the mouth), or problems with digestion and energy. If this is the case, having your local vet examine him for any problems is best to helping get him back to growing well with his brothers and sisters.

Q. I have a cat that defecates in the litter box but always urinates outside the box. It is very annoying.
ANSWER : A. Inappropriate elimination in cats is often a behavioral problem rather than a medical problem, so the first step is to have him seen by your vet to eliminate any kind of illness or condition as a cause for his eliminating outside the box.

If medical issues are ruled out, take a look at other reasons. Has there been a lot of unusual activity? Has you cat been left at home or boarded? Is the litterbox in a busy area? Has anything happened recently in this area to make him reluctant to use it again? Is there another cat, pet or person that is preventing him from getting to the box? Have you changed it from a hooded to an open box, or vice versa? Is it big enough? Have you changed the type or brand of litter? Is there something attractive about the spot he uses? Cats dislike disturbances to their routine and may act out to express their dissatisfaction.

The general rule is one litter box per cat in the household, plus one. That way each cat can have a place of their own to go in case the box is occupied or another cat has claimed it as territory. They should be scooped daily, if not more often and changed completely weekly, washed with soap and water only. You can offer one kind of litter in one box and another kind in another to see if there is a preference. I don’t recommend the crystals, it makes a hissing sound when wet that startles some cats and make them reluctant to use it again. The litter boxes should be located in a quiet, low-traffic area so that the cat can use them in peace. Make sure any other pets or people aren’t giving them a hard time around or in the litter box. It may take some investigation and experimentation to find your cat’s preference and accommodate him so that everyone is satisfied with the situation. And, when cleaning up pet accidents, don’t use any cleaner containing ammonia. This leaves behind a scent similar to urine.

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. My cat seems to have lost control of her bowels and no longer uses her litter box even to urinate. She is 5 or 6 yrs and is in good health otherwise
ANSWER : A. If your cat has had a sudden change in litter box habits, it is always a good idea to rule out any underlying issues with a wellness check from your vet. Bringing in a urine and stool sample if possible can also help as tests can be run on these samples to check for common infections or parasites. If these are present, treating them usually helps resolve the problem of not using the box.

Loss of bowel control usually results in dribbling of feces or urine rather than complete accidents. If you are seeing this, it is possible that an injury to the hind end or problem with the nerves or muscles is happening and should be looked at by your vet.

If the accidents are complete (full amount of stool, big puddle of urine) your cat may be choosing not to use the litter box due to illness, a too-dirty litter, litter pans that are too tall (which may make older cats have a harder time getting in and out), or a litter substrate that was changed too suddenly. Sometimes, changing the environment your cat’s litter box is in by lowering the sides, moving food and water dishes away and returning back to a previously liked litter can help.

In any area of an accident, an enzymatic cleaner should be used. These break down urine and stool particles, making it so that your cat is less likely to be attracted to going there again. Moving stools to the litter box can also entice your cat to start going there again.

Q. My cat started to pee outside the litter box. What should I do?
ANSWER : A. Inappropriate bathroom use in cats is often a behavioral problem rather than a medical problem, so the first step is to have him seen by your vet to eliminate any kind of illness or condition as a cause for his defecating outside the box.

Once medical issues are ruled out, it’s time to take a look at other explanations. Has there been a lot of activity that wasn’t normal? Were you away and your cat was left at home or boarded? Is the litterbox located in a busy area? Has anything happened recently in this area to make him reluctant to use it again? Is there another cat, pet, or person that is preventing him from getting to the box? Have you changed it from a hooded to an open box, or vice versa? Have you changed the brand of litter or kind? Or is there something about the spot he has chosen to use that is attracting him in some way? Cats dislike disturbances to their routine and may act out as a way of expressing their dissatisfaction.

The general rule of thumb is one litter box per cat in the household, plus one. That way each cat can have a place of their own to go in case the box is occupied or another cat has claimed it as territory. They should be scooped at least daily, if not more often and changed completely on a weekly basis, and washed with soap and water.

You can also offer one kind of litter in one box and another kind in another to see if there is a preference. I don’t recommend the crystal kind, since it makes a hissing sound when wet that can startle some cats and make them reluctant to use it again.

The litter boxes should be located in a quiet, low-traffic area so that the cat can use them in peace. Make sure other pets or people aren’t giving them a hard time around or in the litterbox.
