Every summer we start a real fight against parasites like fleas, tick's, worms and skeeters.
Wolfdogs can have it and will if they live in a pretty contaminated place, the contaminated local not need to be necessarely your home but the home of your neighbor and even the street.
When my wolfdogs arrives they're all with winter coat, so was impossible to
see fleas in their, what not mean they haven't, i'm pretty sure that they take fleas in the first time they touch my country, the place we arrive was a possible leishmaniosis area so, we run away to home without stop

.
Some years ago fleas and ticks commonly not appeared in winter, but times change and even at winter we're having huge problems with then, the summer turn in a hell for parasite control.
When they lost the winter coat and turn in an almost Hairless Et dog if they have fleas is possible to see it easly, even when they're under control but a "new flea" jump of the street in theyr, as I have already see.
