To my knowledge, this hasn’t been studied. But I’ll give it my best stab!
Many Parasites like Toxocara canis, the canine roundworm, use milk as a transmission method, and are also able to infect humans (though they are very unhappy in us and just wander around to no avail) so I wouldn’t be surprised if transmission was possible. However, at least with Toxocara, the infective stage to humans is the encysted egg, while the infective stage to puppies is the actual larvae. Does this make a difference? I don’t really know, but the best way to prevent it would be to have your dog on good parasite control and medication before engaging in anything, just to be safe.

Toxocara canis (T. canis, also known as dog roundworm) is a worldwide-distributed helminthparasite that primarily infects dogs and other canids, but can also infect other animals including humans.[1][2] The name is derived from the Greek word "toxon," meaning bow or quiver, and the Latin word "caro," meaning flesh.[3] T. canis live in the small intestine of the definitive host. This parasite is very common in puppies and somewhat less common in adult dogs.[4] In adult dogs, infection is usually asymptomatic but may be characterized by diarrhea. By contrast, untreated infection with Toxocara canis can be fatal in puppies, causing diarrhea, vomiting, pneumonia, enlarged abdomen, flatulence, poor growth rate, and other complications.[1]
As paratenic hosts, a number of vertebrates, including humans, and some invertebrates can become infected. Humans are infected, like other paratenic hosts, by ingestion of embryonated T. canis eggs.[5]The disease (toxocariasis) caused by migrating T. canis larvae results in two syndromes: visceral larva migrans and ocular larva migrans.[6] Owing to transmission of the infection from the mother to her puppies, preventive anthelmintic treatment of newborn puppies is strongly recommended. Several anthelmintic drugs are effective against adult worms, for example fenbendazole, milbemycin, moxidectin, piperazine, pyrantel, and selamectin.[1]
