1. Neonatal period: 1-30 days

The neonatal period is when dogs are just born. At this time, puppies need more care from their owners. Mainly relying on breast milk to live, the body cannot regulate body temperature, and the female dog needs to produce heat to keep warm. No hearing or vision for 1-10 days, only relying on weak touch to find nipples. Eyes open around the 13th day, hearing begins after the 15th day, and teeth begin to grow after the 20th day. From the 21st to the 28th, the amount of breast milk is not enough, and it is necessary to transition from liquid food to semi-solid food. Diarrhea and constipation are easy to occur at this time, so be sure to feed him lactase, probiotics, or give him goat milk powder/pet milk powder. As for constipation, if it occurs when consuming milk powder, you can feed a small amount of vegetable oil and massage the abdomen to help defecation. The first deworming begins at 14-28 days of age.

2. Infant period: January to February

The digestive system of puppies is not fully developed yet and needs careful care from the owner at this time. Generally, the dog should be fed at least three times a day, with smaller meals and frequent meals based on the dog's own condition. Soak the dog food in warm water or goat milk powder, and feed it little by little. Do not feed too much, otherwise the dog will be prone to indigestion. Pay attention to giving your dog plain water, and remember not to feed it milk. Milk can cause diarrhea. You can give him a little probiotics every day to regulate his stomach. At this time, puppies have poor resistance to viruses and germs and should not be taken out, let alone contact with cold patients to prevent the dog from getting sick. Immunization starts at 6-7 weeks of age and ends at 3 months of age. Try to give him a bath after the immunization is over. You can use dry cleaning powder for early bathing. Teeth begin to appear between 19 and 28 days old, and all deciduous teeth erupt at 2 months of age. With certain learning ability, you can start training to go to the toilet at a fixed location

3. Infancy: March to June

At this time, the baby dog ​​can slowly get rid of the blistered dog food and can eat some dry dog ​​food. During this period, the dog's eating time should be slowly adjusted. It is best to make the dog's eating time more regular. At this time, the dog still eats dog food and drinks boiled water. However, at this time, the dog's skeletal muscles are growing rapidly, requiring a large amount of protein and calcium, and the coat is gradually replaced by adult dog hair. During the critical period of hair beauty, an embarrassing period appears. And during the period when puppies develop a desire for dominance, they begin to try to own their own territory and dominate their owners. The destructive ability increases. At this time, the dog's body length and height are rapidly growing, and the baby fat is receding, so it needs moderate exercise every day to maintain growth and development.

4. Sexual maturity period: August to 14 months

At this time, the dog enters sexual maturity and appears for the first time in heat. The first estrus is prone to hormone imbalance, causing estrus disorders. Those with persistent estrus, no estrus, or false pregnancy have low pregnancy rate and high dystocia rate. It is necessary to supplement him with nutrients that promote reproduction: vitamin E, organic chromium, folic acid, etc. Be sure to pay attention not to breed during the first estrus, and pay attention to hygiene during estrus to prevent infection. If you are infertile, you can perform sterilization after the estrus is over

5. Adolescence: 6-18 months

Now dogs canCompletely eat dry dog ​​food, but you can also feed some meat to enrich nutrition, such as cooked beef and chicken. However, be careful not to feed chicken or duck bones to your dog, as this can lead to skeletal dysplasia. If it is really necessary (the dog is malnourished, sickly, picky eaters, etc.), you can feed some nutrients appropriately. According to the actual condition of the dog, choose nutritional supplements that supplement vitamins, calcium, protein or hair care. Don’t be greedy for too much, and don’t supplement a large amount of nutrients at once just because you feel sorry for your dog. You need to take care of your dog slowly and slowly. At this time, the dog's skeletal muscles are growing rapidly and require a large amount of protein and calcium. And they have strong curiosity, strong cognitive ability, and deep memory. It’s the best time to study

6. Adult dogs: dogs aged 1 to 6 years old

Dogs are adults when they are 1 year old, and they will grow into shape at almost one year old. Their body size will not change much in the future. At this stage, you can still eat dog food normally, and there are no too many dietary taboos. However, you still need to pay attention to supplementing nutrients in an appropriate amount, do not feed chicken and duck bones, avoid salty and spicy food, feed cooked food instead of cold food, and avoid eating animal fat. If you have a cold or illness, you should be sent to a pet hospital for medical treatment in time. You must not use medication blindly at your own discretion. Unless you are a veterinarian yourself, you must be responsible for your pet.

7. Old age: 8-18 years old

Dogs over 8 years old are already over 50 years old in human years and should enter the old age of "dog birth". At this time, the functions of the dog's various organs begin to slowly decline, and aging diseases appear, such as diabetes, weakened liver and kidney function, bone and joint diseases, etc., and are prone to diabetes, liver and kidney disease, high blood pressure, fractures, joint inflammation and other diseases, so at this time Pay special attention to calcium supplementation. You can choose to eat more soy products and cartilage, or you can choose nutritional supplements on the market to supplement calcium for dogs. Spend more time in the sun, take walks, and pay more attention to hygiene. I believe your dog will stay with you longer.
