Parvo, a shortened name for ‘parvovirus’, in dogs is a highly contagious virus that spreads rapidly in dogs, especially when they have poor health or are living in poor conditions. You will want to keep your beloved pooch safe.
In this article, we examine parvo symptoms, learn how dogs contract parvo, identify the early signs, and discuss parvo treatment. Read on to find out more and find out how to keep your puppy or dog safe and healthy.
Parvovirus is a viral disease that affects the GI (gastrointestinal tract) or the cardiac system of a dog, causing breathing difficulties. It is not necessarily the virus itself that kills puppies and dogs but the symptoms it causes, such as sepsis, pneumonia, or severe dehydration. These complications can lead to death.
Puppies are particularly vulnerable, from 6 weeks to 6 months of age when their immune system is developing.
It is essential to have your puppy vaccinated to protect them from parvo early. And if your puppy or dog does develop symptoms, it is key you seek prompt veterinarian attention.
Dogs or puppies usually pick up the virus from faeces left by an infected dog. Parvo symptoms appear between 3 and 7 days after exposure.
Learn to recognize the symptoms and know when to contact a local veterinarian. If you suspect parvo it is wise to seek help promptly, as the illness can become serious quite quickly.
The symptoms to look out for include lethargy and unusual sleepiness, loss of appetite, fever (high temperature), vomiting, diarrhoea, bloating and abdominal discomfort (pain). You might also notice rapid weight loss or your puppy becomes so weak it collapses, which is a severe symptom and requires urgent treatment. They may be suffering from dehydration due to vomiting and diarrhoea.
Parvo is a highly contagious and persistent virus. Dogs contract the virus by having contact with the faeces of an infected dog. So, they might sniff or lick an area contaminated with infected faeces.
They may also come into direct contact with an infected dog. The virus could also be on other surfaces, a person's hands or clothing. High-risk areas are kennels and dog parks.
Puppies are the most vulnerable to parvo, especially between six weeks and six months of age. Their immune systems are still developing, and they may not have completed their vaccination series. Unvaccinated adult dogs are also at risk.
Some breeds are more susceptible. These breeds include Rottweilers, Doberman Pinschers, American Pit Bull Terriers, Springer Spaniels, and German Shepherds.
Puppies produced by irresponsible breeders in puppy mills are at much higher risk than other puppies. If they catch parvo, they are at a much higher risk of death. The breeding facilities are often places of poor sanitation and stress. Often, weaning is very early. Not enough attention is given to the puppies or mum either.
A responsible puppy breeder will be transparent in their practices and happy to answer all your questions. They will likely be licensed, have AKC registration and be educated as a dog breeder. They should show you where the puppies were raised, allow you to meet the parents and have full health records. By choosing a responsible breeder your puppy will have had a great start in life and a stronger immune system.
It is much better to prevent your puppy or dog from catching parvo. So, how do we prevent infections in dogs? The most important defense against parvo in dogs is vaccination. So, purchase a puppy from a responsible puppy breeder who has already started your puppy’s vaccination treatment.
Continue with the vaccination schedule as advised by your veterinarian.
While your puppy is young, keep them on the lead for their walking training and avoid high-traffic areas such as dog parks and pet stores. You should also regularly clean your puppy’s environment with a pet-safe disinfectant.
If you suspect your puppy or adult dog is experiencing symptoms, you should seek veterinarian care. There is no cure for parvo, but treatment tends to reduce symptoms. They may require vet care that can include IV fluids to treat the dehydration due to vomiting and diarrhoea. Medications can provide pain relief and reduce fever. Antibiotics offer treatment for secondary infections. There is also anti-nausea medication.
Parvo in dogs, or parvovirus, is a highly contagious and invasive virus that puppies aged 6 weeks to 6 months are highly susceptible to. There is no cure for parvovirus, which is why vaccinations for puppies and dogs are so essential. The symptoms can be frightening and take hold rapidly.
If you think your puppy or dog has developed symptoms, seek prompt veterinarian treatment.
Purchasing a puppy from a reputable and responsible breeder can ensure that your puppy has had a great start to life, leaving their mum at the right age, being weaned correctly, and starting their vaccinations at the right age.
