Risk of resistance development? NO
There are reports on resistance of Ancylostoma spp to pyrantel in dogs and horses, but so far it does not seem to be widespread, and the simultaneous administration of a benzimidazole (febantel) with a different mechanism of action than pyrantel should ensure efficacy against potentially pyrantel-resistant worms.

Febantel is a broad-spectrum anthelmintic belonging to the chemical class of the benzimidazoles that was introduced in the 1970s (by BAYER). In fact it is a pro-benzimidazole (a so-called pro-drug) that becomes a benzimidazole only once ingested by the host. It is transformed into fenbendazole in the stomach and the intestine of the host, shortly after ingestion. Febantel is effective against numerous roundworms (e.g. Toxocara canis, Toxascaris leonina), hookworms (e.g. Ancylostoma caninum, A. braziliense, Uncinaria stenocephala), and whipworms (Trichuris vulpis). Febantel is moderately used in pets and livestock, but not in agriculture.
Pyrantel is a narrow-spectrum anthelmintic belonging to the chemical class of the tetrahydropyrimidines that was introduced in the 1960s (by PFIZER → ZOETIS). It is effective against roundworms and a few tapeworms (depending on the dose) in the gut, but not against those in other organs (e.g. the lungs, the skin, etc). It adds efficacy against important dog worms such as the roundworms Toxocara canis and Toxascaris leonina, the hookworms Ancylostoma caninum and Uncinaria stenocephala. It is used a lot in pets and horses but rarely in livestock. It is not used in agriculture.
Praziquantel is a veteran isoquinoline anthelmintic introduced in the 1970s (by BAYER). It is still the most effective and most vastly used parasiticide against tapeworms, but without any efficacy against roundworms, fleas or ticks. Praziquantel adds efficacy against tapeworms (Dipylidium caninum, Taenia pisiformis, Echinococcus granulosus, Echinococcus multilocularis) but has no efficacy whatsoever against roundworms, hookworms or whipworms. It is the anthelmintic most vastly used against tapeworms on pets. There are hundreds of antiparasitic brands for pets containing praziquantel. It is also abundantly used in horses, but scarcely in livestock. It is not used in agriculture.
Pyrantel, praziquantel, all the benzimidazoles (e.g. febantel, albendazole, mebendazole, etc.), piperazine, and other anthelmintics have no residual effect, i.e. they act against the worms during a few hours after administration but are quickly metabolized and excreted. For this reason treatment must often be repeated for certain indications. This is in contrast with wormers containing macrocyclic lactones (e.g. milbemycin oxime, selamectin) that ensure efficacy against numerous roundworms during weeks after a single treatment.
