Factors Affecting Development

Jack Russell genetically cannot be large and powerful dogs. But it is important for the owner to monitor the full set of mass, growth from the suction period. On the development of the “milk” puppy has influence a lot:

  • quality, volume of milk in the mother dog;
  • the number of coats in the litter;
  • helminth infection;
  • lack of vitamins, minerals, nutrients;
  • conditions of detention;
  • rivalry (the largest puppies often oppress small, weak);
  • congenital diseases;
  • fear, stress.

It is important for the breeder to correctly determine the developmental delay of the baby, to eliminate it in time: put the kitten to the mother’s rear nipples (they have more milk), conduct antihelminthic prophylaxis, add in complementary foods vitamin complex. If the cause is poor quality milk, newborn puppies receive artificial feeding. There is every chance that a weak kitten will develop into a healthy one, full dog.

When puppy development began to lag behind the norm after moving into a new home, the first reason is the severe stress of separation from the dog family, changing conditions, transferring to new food. Monthly baby already needs people – it needs to be ironed, worn, played, be sure talk to him in a gentle voice.

The second reason is inadequate, unbalanced nutrition. Puppies are transferred only to premium food recommended a veterinarian.
