Puppy growth is the most important period when the whole complex of physiological, psychological and behavioral reactions inherent in the breed develops.
It is in the first months of life that a puppy should receive the foundation of a good education. A growing puppy is curious and its energy hits over the edge.
He explores new places, plays with other puppies of his litter, learn a lot from his mother. At this age, the child especially needs custody of its owner in order to successfully assimilate the norms of social behavior and become a well-bred dog.
The growth rate of the puppy depends on the breed. Small puppies grow a little faster than medium-sized puppies and much faster than very large puppies.
Puppies of dogs of small breeds reach the size of an adult animal at the age of 8 - 10 months. In dogs of medium breeds, this occurs at 12 months, in puppies of dogs of large breeds at 15–18 months. While for very full puppy development for very large breeds of dogs it takes 18 - 20 months.
The age of puberty dogs also vary. The first estrus in females begins at the age of 6 - 12 months, that is, before the completion of the growth of the organism. Males become sexually mature at the age of about 7 months for small breeds of dogs or 12-18 months for dogs of medium and large breeds.
There are several phases of growth
Their most important characteristics are changes in the energy needs of the animal, the formation of its skeleton and the development of muscle mass. The future physique of a puppy, its health completely depends on the successful completion of the phases of its growth, in which feeding plays a key role. During the first phase of growth, between weaning and the first appearance of permanent teeth, the puppy grows literally before our eyes. His skeleton is developing rapidly and the animal is gaining weight every day.
To maintain an intense metabolism, a puppy requires twice as much energy as an adult dog of the same weight and carefully adjusted dosages of phosphorus and calcium in the diet. Portions of his food should meet the puppy's energy needs, but not exceed the rate so that he does not gain weight too quickly. That is why factors such as multiplicity of diet and quality of feed are so important. Too much calcium in the middle of the growth phase can lead to osteo-articular diseases, and overfeeding to digestive disorders.
During the 2nd phase of puppy growth, the skeleton is strengthened and muscles develop. The dog is still growing, but much slower. When the growth and strengthening of the skeleton ends, the development of musculature continues. During this period, the animal needs a little less energy, but still more than an adult dog of the same weight. During this period, the puppy's body is still very fragile and its weight must be constantly monitored. Being overweight can have very serious consequences. First of all, do not give the puppy any handouts between feedings. The only thing he needs during this period is the right diet, which should be divided into strictly calculated portions.
Schedule puppy weight changes by week. This information is very useful for the veterinarian, as he will be able to determine any possible excess weight. An overweight puppy is at high risk of obesity in adulthood. To avoid this, it is necessary to strictly observe the diet, the frequency of feeding and the volume of servings. Croquet food must be appropriate for puppy size and age.
