Parvovirus in dogs may be caused by improper diet, catching cold, infection from other dogs, internal parasite infection, etc. After the dog is sick, it will show symptoms such as vomiting, diarrhea, loss of mental appetite, and blood in the stool. If not treated in time, it is very likely to die. Therefore, in order to prevent dogs from getting sick, it is recommended that owners vaccinate their dogs regularly.

1. Improper diet

1. Eat leftovers

Leftovers are easy to spoil and may contain a large number of bacteria, which can easily cause parvovirus once eaten by dogs.

2. Eat greasy food

The dog’s gastrointestinal condition is relatively poor and cannot hold oil. Greasy foods like meat can easily damage the gastrointestinal health of dogs, causing gastrointestinal discomfort and symptoms of vomiting and diarrhea, thus increasing the risk of parvovirus.

3. Eat all kinds of bones

Bones are very dangerous for dogs, especially chicken, duck, and fish bones. If eaten, they can easily scratch the dog's intestines and cause gastric perforation. If it is other bones, dogs will become constipated if they eat too much, and in severe cases, their anus may rupture.

4.Drink milk

Milk is a food with high molecular content, which is difficult for dogs’ intestines to absorb. And milk also contains a lot of lactose. Dogs cannot absorb that much lactose, which can easily cause symptoms of lactose intolerance such as diarrhea and vomiting.

2. Catch a cold

After a dog catches a cold, the gastrointestinal tract will be more sensitive, and diarrhea, vomiting, and gastrointestinal discomfort may occur, which may induce enteritis and parvovirus in the dog.

3. Infected by other dogs

Parvovirus spreads very quickly and is usually contracted through contact with the feces, urine, vomitus, secretions, etc. of sick animals. If a healthy dog ​​comes into contact with a sick dog, it can easily become infected with parvovirus.

4. Caused by internal parasites

Regular deworming of dogs is very worthy of the attention of pet owners. If the dog is not dewormed regularly, it will lead to a lack of antibody immunity in the dog's gastrointestinal tract, allowing parvovirus to take advantage of it. At this time, parasites will multiply and destroy gastrointestinal health, and eventually the disease will become enteritis-type parvovirus..

Note: Dog parvovirus is an infectious disease with a very high contagious rate. It is highly contagious and leads to a very high mortality rate for dogs. Generally young dogs, malnourished dogs, unvaccinated or failed vaccines are easily infected.
