Pregnant and nursing dogs can transmit hookworm and roundworm larvae to their puppies during pregnancy if the larvae migrate across the placenta. Whipworms typically grow to maturity in the upper part of the large intestine.
Roundworm infections can develop when the ingested eggs hatch and the larvae migrate through the tissues of other organs, often a dog’s lungs and liver, before returning to the small intestine to grow to maturity. Transmission of intestinal worms (hookworms, roundworms, and whipworms) commonly occurs when your dog ingests contaminated soil or feces containing eggs or immature worms (larvae) that have been passed from other infected animals in the environment.
Here are some of the most common ways that dogs get worms: Eating Feces Here’s what you need to know about worms in dogs: how to tell if your dog has worms, how dogs get worms, and how to get rid of worms in dogs. As gross as that thought may be, intestinal worms are pretty common. "Therefore, when the treatment protocol was harmonized in the new legislation, the overall effect of increasing the treatment window in the case of the UK, Ireland and Malta from two days to five days increased the probability of introduction of the parasite into these countries.One of the most common concerns that you may face as a dog owner is whether or not your dog has worms. "The negative effect of increased treatment windows is much bigger for dogs returning to a free country than are the positive effect for dogs from endemic areas visiting a free country. Unfortunately, most dogs crossing the border to the UK appear to belong to the latter group. "For dogs returning to counties where no findings of the parasite have been recorded very large improvements in compliance is needed to prevent the risk from increasing when increasing the treatment window. "While the UK data suggests that an increased treatment window from 24 hours to 120 hours has increased the number of dogs in compliance, as the overall number of travelling pets has also increased, this has had less effect on the proportion of animals in compliance. The scientists wrote: "The model results, supporting previous reports, show that introduction will take place in spite of existing barriers with a probability close to 100 per cent.
In 2011 the EU introduced standardised checks across all 28 member states, meaning that it now takes up to five days to screen dogs for the deadly disease, rather than the 48 hours previously stipulated under UK law.
