1 month

Newborn collies sleep for nearly the whole day and are blind for about two weeks. Puppies get plenty of love and attention from their mother, but they also start to realize that friends are people.

The animals start to run, crawl, and go to the bathroom on their own during the second week. They start to recognize their mother, their "tribesmen," and other people. The dog’s character development can be impacted by a strong fear or fear of anything, which the owner shields them from.

The puppy weighs no more than two kilograms. For the babies, mother’s milk is sufficient at first. When the collie opens its eyes and begins to run, supplement feeding is gradually added while keeping an eye on the animal’s response. For puppies under a month old, it is best to use a specially balanced food. Feeding schedule: up to six feedings per day.

2 months

The proprietor is able to hold the infants in his arms and give them cuddles. Dogs are gradually trained by an individual who establishes rules, provides incentives for good behavior, and sets boundaries. The animal starts to comprehend dog behavior patterns, the purpose of barking, what a bite is, and what it feels like to be bitten.

Babies gain two to three kilograms of weight. The puppy’s diet already includes a full, balanced feed that replenishes its energy expenditures. They can use a big "sugar" bone to hone their teeth.

3 months

By now, the young animal is familiar with the social dynamics of its kind and has picked up skills in interacting with dogs and other members of its family. fully confides in others and starts to comprehend their role in their lives. The dog can be trained to obey basic commands and use a leash.

Puppies of collies weigh between 4 and 5 kg. Feeding frequency is lowered to four or five times per day. You can include a small amount of chopped greens and vegetable meat in your diet. Giving the dogs a drop of "Calcefite-15" and "Trivitamin" is beneficial.

4 months

It’s critical to keep the animal safe from potentially harmful circumstances that terrify them. Together, you must overcome its anxieties. However, you shouldn’t look after the collie because it starts to "feel out" how far it can play games with people. The owner stops the animal from biting or fighting by saying "no," "No," and the animal ignores him for a few minutes following the trick.

The average weight of young dogs is 7 kg. They can vary their diet in the ways listed below:

raw meat (portion – not more than 100 g);
milk cereals;
Calcinated cottage cheese;
Egg raw yolk.

To prevent animal poisoning and infectious diseases, the owner must ensure that the puppy is fed only unprocessed products from a reputable supplier.

5 months

The dog might attempt to control kids or other animals. The owner prompts family members to refrain from being overly gentle with their pet and ends this behavior. Should the dog exhibit signs of aggression or excitement, it is best to ignore it.

Because the puppy is active, larger portions are needed to help it regain strength. Additionally, it is fed cottage cheese, porridge, and raw meat (the portion size is increased to 200–250 g). It is a small amount of honey added to dairy products to make them sweeter. You can occasionally give the puppy small amounts of the boiled, boneless fish if it enjoys it.

6 months

The dog starts to exhibit personality at six months of age; this is comparable to the "problematic" adolescence that occurs in people. It’s critical that the owner set clear boundaries for what the puppy is permitted to do, but they shouldn’t get too caught up in the "who is the boss here" game.

Since it is still growing, the animal has a larger appetite than an adult dog. Its portions should, however, be in line with its level of physical activity. To support overall growth and preserve the condition of the coat and teeth, supplements containing the fatty acids Omega-3 and Omega-6 are added to the diet.

Throughout their first year of life, collie puppies undergo remarkable transformations, growing from tiny, energetic balls of fur to elegant, perceptive canines. With the aid of adorable pictures that document their development from one to twelve months old, this article tracks their growth month by month, stressing significant turning points like physical development, social behavior, and training advancement.

The energetic teenage dog is eager to see the entire world. It is crucial that the owner eventually acclimates the animal to a muzzle or leash. More sophisticated commands are given to the animal by the person. It’s critical to recognize that the dog has developed into a fully functional companion.

The collie teenager is growing quickly at this time, and since the animal’s skeleton is still developing, it is important to make sure his diet has enough calcium and phosphorus, which are found in offal, dairy products, and muscle cuts.

Portion sizes for meat and fish are raised to 300–350 g. Beneficial dietary supplements: two drops of "Calcefita-15," "Trivitamin," or "Dogvital" preparations.
