What are pet parasites?


Worms are a tricky parasite as your pet may not show any symptoms of infestation at all. Some worms are transferred via prey like mice or rats, fleas can carry tape worm eggs, and others can be transferred in high-risk areas where there is lots of animal traffic such as dog parks.

Worms are potentially harmful to both animals and humans and can cause severe health issues.

Fleas Vs Worms


Fleas are parasites that live externally on the skin of an infected animal. A flea bites your pets’ skin in order to feed itself, this can be irritating and painful to animals while also causing damage to their skin. Unlike worms, fleas are visible to the naked eye and move quickly around your pets’ coat.

Keeping your pet protected from parasites

Treatment of parasite infestations can end up being a costly and lengthy process, not to mention distressing to your pet and in some cases life threatening. This is why prevention is the best way to protect your pet from parasites. There are a wide range of options available to treat all of these parasites from tablets, to oral chews and spot treatments. Depending on the brand and type you’ve chosen, you may find that there is one treatment that covers your pet for all of these parasites at once, others you may have to administer separately.

Regardless of the choice of prevention treatment, pet parents need to be vigilant with administering the treatment at the right time. Each treatment is different, and you should be aware of and follow the instructions for your specific brand and type. This will ensure that your furry family member is properly protected all year round.
