What colors do dogs see at night?
When night falls on the earth, human vision is gradually blurred by darkness, but our loyal canine companions are still active. What does the world look like to dogs on those moonlit or starlit nights?
As winter approaches quietly, the cold wind begins to howl, snowflakes fall in a flurry, and the whole world seems to be covered in a layer of silver. In this cold season, we unconsciously wrap ourselves in cotton clothes, wear thick scarves and gloves, trying to resist the invasion of the cold. And our beloved dogs, as an indispensable member of the family, constantly touch our hearts with the warmth and coldness of winter. A common question arises: Do dogs need to wear sweaters in winter?
Dogs' fur is their first line of defense against the cold. Different breeds of dogs have varying textures, lengths, and densities of their fur, which also determines their differences in tolerance to cold. Dogs such as Alaskan Malamute and Huskies, which originally lived in cold polar regions, have double layered thick fur. The outer layer of hair is thick and hard, which can effectively block the invasion of wind and snow, while the inner layer of fur is soft and warm, just like wearing a natural down jacket, providing them with strong insulation ability in extremely cold environments. For these dogs, in a typical winter environment, their own fur is sufficient to maintain body temperature and they do not necessarily need extra sweaters to keep warm. Even in the cold outdoors, they can still run and play happily, enjoying the fun of winter to the fullest.
However, not all dogs have such powerful thermal equipment. Small dog breeds, such as Chihuahuas and Yorkshire, have relatively short and thin fur, a thin fat layer on their bodies, and weaker resistance to cold. In the cold winter, their small bodies easily lose heat, and their trembling appearance makes people feel heartbroken. There are also some short haired dog breeds, such as French Bulldogs and Baggins, whose fur cannot provide sufficient warmth. In low temperature environments, their body temperature rapidly drops, which may cause health problems such as colds and pneumonia. For these dogs, a suitable sweater is like the warm sun in winter, adding warmth and allowing them to feel comfortable and at ease even in the cold season.
In addition to breed factors, the health status of dogs is also an important consideration in determining whether they need to wear sweaters. Older and weaker dogs experience a gradual decline in their bodily functions and a decrease in their ability to regulate body temperature, making them more susceptible to feeling cold in winter. At this moment, a soft and comfortable sweater can help them maintain their body temperature, reduce the burden on their bodies, and allow them to live comfortably in winter. In addition, dogs that have just recovered from illness have weaker bodies and lower immunity, and cold stimulation may affect their recovery process. Wearing sweaters for such dogs is our way of giving them extra care, hoping that they can recover their health as soon as possible in warmth.
The living environment of dogs cannot be ignored either. If dogs spend most of their time living indoors in a warm environment with a suitable temperature range, their demand for sweaters may be relatively low. But even indoors, we should be aware that there may be drafts in some places, or the floor may be cold, and dogs may catch a cold while lying on the ground for a long time. In this case, a lightweight sweater can provide extra warmth for dogs, allowing them to move freely indoors without worrying about the cold.
When we decide to buy or make sweaters for dogs, there are also some details to pay attention to. Firstly, the material of the sweater should be soft and comfortable, avoiding the use of rough and highly irritating materials to prevent rubbing against the dog's skin, causing discomfort or allergies. Natural materials such as pure cotton and wool are good choices, as they not only provide good warmth but also are gentle on dogs' skin. Secondly, the size of the sweater should be appropriate. A sweater that is too large can affect the dog's movements and easily cause them to trip over; A sweater that is too small can bind the dog's body, affecting breathing and blood circulation. We can carefully measure the dog's chest circumference, neck circumference, and body length, and choose the appropriate sweater based on these dimensions. In addition, the style of sweaters should also consider the activity needs of dogs, and try to choose loose and easy to put on and take off styles to facilitate their daily activities.
During the process of putting on a sweater for a dog, we can also feel the deep emotional bond between us and the dog. When we gently coat our dogs with sweaters, they may look at us curiously, their eyes filled with trust and dependence. We can dress our dogs in sweaters while softly communicating with them, making them feel our care. Dogs wearing sweaters may become more lively, as they curiously examine themselves in front of the mirror or run around happily, showcasing their new look. Watching our dog become warm and happy because of our love, our hearts are also filled with happiness and satisfaction.
There is no absolute answer to whether dogs need to wear sweaters in winter, but we need to consider factors such as dog breed, health status, and living environment comprehensively. Whether dogs need to wear sweaters or not, our care for them will not change. In the cold winter, we hope to create a warm and comfortable environment for dogs through various means, so that they can spend every winter healthy and happy. When we see dogs still full of vitality in winter, licking our hands with warm tongues and wagging their tails to express love, we know that all the care and effort put in for them is worth it. Let us use this deep love to accompany our dogs through every beautiful season, and make our companionship with dogs longer and more beautiful.
When night falls on the earth, human vision is gradually blurred by darkness, but our loyal canine companions are still active. What does the world look like to dogs on those moonlit or starlit nights?
In the human sensory world, vision dominates. We use our eyes to capture the colorful world and use light and shadow to outline the contours of everything.
When we look into our dogs' eyes, their bright and lively eyes seem to be able to speak, conveying dependence and trust.
When you come home after a busy day, you open the door and see your dog lying quietly on the floor, wagging its tail and looking at you. The warmth and healing of that moment are the most cherished moments for countless dog owners.
When a dog that is usually lively and active suddenly loses its appetite, becomes listless, or even vomits frequently, every pet owner will be worried that it is intestinal obstruction, a "health killer".
When we caress the furry ears of dogs and enjoy the warm moments of cuddling up with each other, our hearts are filled with happiness.
