How to Choose the Right Dog: Puppies, Adults, Size, Breed
Keeping a dog requires taking on corresponding responsibilities and is not as simple as taking it out for a walk.
The future of a pet is entirely up to its owner. So if you plan to adopt a dog, you must know that being a good pet owner requires time, energy and patience.
So before getting a pet, you should consider the age, gender, breed and other factors of your dog and make a careful choice.

Ⅰ. When it comes to choosing a dog for the first time, which is better, an adult dog or a puppy?
Puppy
Most people would think that it is better to choose puppies than adult dogs.
Advantages:
First of all, puppies are very cute, adaptable and easy to train. More importantly, they can develop a deep bond with their owners.
Disadvantage:
But at the same time, it will also face problems such as weak constitution, easy illness, poor self-care ability, and the need for more care. It also takes a relatively long time to establish a good relationship with the puppy.
Adult dog
Advantages:
Relatively speaking, adult dogs have stronger living abilities.
Disadvantage:
But it’s not easy to build an emotional bond with it either. Some bad habits that have already been formed may need to be constantly corrected by the owner.
One point to note is that after a dog reaches the age of two, its behavioral habits and temperament are basically formed. They do not have as much behavioral flexibility as puppies, and the habits of adult dogs are often not easy to change.
Of course, if you choose an elderly dog, it might be another challenge. You need to give it double the care and attention for it to be happier.
So, when choosing between a puppy and an adult dog, the key lies in the needs of the owner. The prerequisite for choosing a puppy is knowing how to train it, having time for training, and having sufficient understanding of dog breeding.

Ii. When getting a dog for the first time, is it better to choose a male or a female dog?
Whether male dogs or female dogs are easier to raise, everyone has their own opinion. For first-time dog owners, they may struggle for a while when it comes to choosing between a male and a female dog. Let’s take a look at the comparison of the advantages and disadvantages of male and female dogs below, hoping to provide some reference for future owners.
1 Shape
Like other animals in nature, male dogs are generally taller than female dogs and have prettier fur.
Adult male dogs will be stronger, more powerful and handsome.
2 Character
Male dogs are rather naughty, active and love a lively atmosphere. At the same time, male dogs have a strong instinct – to occupy territory. They will constantly expand their territory, so sometimes they can’t avoid fighting with other dogs. If a male dog is scolded by its owner, it will further stimulate its possessiveness, making it more aggressive and gradually it may no longer be so obedient.
Female dogs, on the other hand, are more obedient, easier to tame and cleaner.
3 Fertility
Female dogs come into heat approximately twice a year, meaning they give birth to a litter of puppies every six months. After giving birth to puppies, a female dog sheds a lot of hair and is not as beautiful as before.
After the age of one, male dogs may be overly attentive to female dogs regardless of the time and occasion.
The above are the characteristics of male and female dogs, each with its own advantages and disadvantages. It is hoped that future owners will choose according to their personal preferences.

Iii. What size of dog is better to choose?
Dogs come in different sizes. Some people prefer large dogs while others like small ones. The feeling of raising them is completely different. Let’s take a look at the differences between keeping large dogs and small dogs.
1. The feeding costs are different
The biggest cost of feeding a dog is dog food. The dog food for a large dog in a day may be equivalent to that for a small dog in a month.
2. Different weights
Large dogs can be picked up when they are young, but when they grow up, they have a strong presence and are more like companions to their owners. They can’t be held even if you want to.
Even when they grow up, small dogs can be easily held in one’s arms and enjoy doting like pets.
Another difference brought by weight is that large dogs will touch their owners if they need something, much like a heavy pat. However, when a small dog touches it, it hardly feels anything.
3. Different amounts of exercise
Large dogs generally have a high demand for exercise, so it’s best to take them out to play every day. Otherwise, the excessive energy might cause them to cause trouble at home.
Whether a small dog goes out or not does not depend on its amount of exercise, but on its owner’s mood, because it can meet its exercise needs at home.
4. The feelings when being coquettish are different
A large dog is coquettish and asking for a hug, which is more like throwing its owner. Its kiss is more like washing its owner’s face.
When a small dog acts coquettishly, the owner can easily handle it with one hand and hold it for as long as they want.
5 The amount of stool varies.
Large dogs have a lot of feces, which is more troublesome to deal with, especially when they are out and about, as it can easily cause embarrassment.
Small dogs, on the other hand, produce much less feces, causing much less embarrassment for people.
Other differences include that large dogs have a good hand feel and can warm hands in winter.
Small dogs tend to bark more easily, especially when they first go out and take the elevator. Small dogs are more prone to tension. When stimulated, they are more likely to attack people and specifically bite the parts below the legs, making it very difficult for people to prevent. The probability of small dogs hurting people is much higher than that of large dogs.
There is one more difference. Generally speaking, large dogs have a shorter lifespan.
I previously posted an article about the lifespan of dogs. You can take a look: Do you want to know how old your dog corresponds to a human?

Iv. Is it better to choose a mixed-breed dog or a purebred dog?
Some people pursue purebred dogs and are even willing to spend a lot of money to buy them. Some people think that mixed-breed dogs are healthier than purebred dogs. This is called “hybrid vitality”. Purebred dogs are more likely to suffer from certain genetic diseases caused by certain genes than mixed-breed dogs, so they will buy mixed-breed dogs.
Researchers conducted extensive studies on the issues of mixed-breed dogs and purebred dogs, and finally narrowed the scope of the analysis to the most common genetic diseases among dogs. The research results show that the risk of genetic diseases is widespread in the general dog population and confirm that the probability of diseases in mixed-breed dogs and purebred dogs is almost the same.
So, whether it’s a mixed-breed dog or a purebred one, as long as the dog is in good health and can meet its own needs, that’s fine. In fact, there is no such thing as purebred dogs in the true sense. Many so-called purebred dogs are also artificially bred by crossing two breeds of dogs.
