How to choose the breed of meat dogs

At present, most professional dog owners raise local native dogs, but not all native dogs are suitable for meat. Some dogs are small and slow in growth, and their weight can not meet the requirements for a long time. Therefore, in the introduction of dog breeds, careful selection must be made. The main contents of selection are:

(1) Health status

1. Mental state. Healthy dogs are lively and responsive, and their tails are naturally erect and wobble from side to side. Sick dogs are depressed, like lying, do not want to move, thin, drooping tail or head standing, slow to respond to external stimuli, ignoring or too sensitive to things around, panic, blind activities, running wild.

2. Eyes. Healthy dogs have bright, bright eyes, no tears, pink conjunctiva and no secretions in the corners of the eyes. The sick dog's eyes are blank, gazing and standing, the corners of the eyes often have eye droppings, or shyness tears, conjunctiva flushing or blue-purple. The conjunctiva of anaemic dogs is pale.

3. Nose. The nose of a healthy dog is moist and cool, and there is no secretion from both nostrils. If the nose is dry or even cracked, or a large amount of gray-white mucus or purulent nose flows from the nostrils, the dog may have a febrile infectious disease.

4. Ears. The ears of healthy dogs are clean and odorless, while the ears of small dogs are often erect and can move cleverly in the direction of human call, and there are no crusts and secretions on the outside or inside of the ears.

5. Oral cavity. The mouth of healthy dogs is clean and moist, the mucous membrane is pink, bright red, no tongue coating, no bad breath, white teeth, no incomplete closure and salivation when the dog mouth is closed. If you see yellow tongue coating and smell, it is a sign of gastritis. When suffering from stomatitis and pharyngitis, the temperature of the mouth increases, the mucosa flushes, and the mouth often accumulates a large amount of sticky saliva, which flows out in the form of filaments.

6. Skin and coat. The skin of healthy dogs is soft and elastic, the skin is neither cold nor hot, the feel is mild, the coat is fluffy and shiny. If the skin is dry, poor elasticity, rough and messy coat or hair removal, broken hair, skin rash, scab, the performance of severe itching, etc., is a sick dog.

7. Anus. The anus of healthy dogs is tight, the surroundings are clean, and there are no foreign bodies such as feces. When dogs suffer from digestive tract diseases such as dysentery, it is common to have loose anus, dirty surroundings, and even pollute tail hair.

8. Appetite. Healthy dogs can eat and drink, have a strong appetite, and can finish the food in a short time, leaving no leftover food on the plate. After eating, the stomach is full, and the amount of dry feces and urine are appropriate. If the dog leaves the plate without eating immediately or after a few bites after feeding, or if there is a large amount of food left on the plate, it is a sign of illness.

(2) Age

Raising meat dogs should start from the weaned puppies, which is not only easy to raise, but also easy to manage. But sometimes it is necessary to introduce breed males and bitches of appropriate age, which requires age identification. The age of a dog can usually be determined by its appearance and the growth and wear of its teeth. The coat of a strong dog is smooth, shiny, flexible, energetic and has bright eyes. However, the exact age can not be determined by appearance identification, and the growth and wear degree of teeth are often an important basis for determining the age of dogs.

There were 28 teeth in juvenile dogs and 40 teeth in adult dogs. The puppies began to grow teeth at the age of 20 days, the first and second deciduous teeth grew evenly from 4 to 5 weeks of age, and the third deciduous incisors grew from 5 to 6 weeks of age. At the age of 2 months, the deciduous teeth are white, thin and pointed. The first breast incisor was replaced from 2 months to 4 months old. The second and third breast incisors and deciduous canines were replaced from 5 months to 6 months old. From 8 months old to 1 year old, all patients were replaced with permanent teeth. The 1-year-old permanent teeth are neat, white and bright, and the incisors are pointed. The 1.5-year-old mandibular first incisor has a large peak wear and is flush with a small peak. The peak of the second mandibular incisor was worn out at the age of 2.5 years. The peak of the first maxillary incisor was worn out at the age of 3.5 years. The peak of the second maxillary incisor was worn out at the age of 4.5 years. The peak of the first maxillary incisor was worn out at the age of 3.5 years. The peak of the second maxillary incisor was worn out at the age of 4.5 years. At the age of 5 years, the peak of the third mandibular incisor was slightly worn, and the first and second incisors were rectangular. The peak of the maxillary third incisor was worn at the age of 6, and the canine teeth were obtusely round.
