Naruto had a deeper reason for disliking toads.
Among the Shinobi World's three great sage lands were the White Snake Sage of Ryūchi Cave, the Slug Sage of Shikkotsu Forest, and the Toad Sage of Mount Myoboku.
Only the toads of Mount Myoboku were deeply involved in the Shinobi World's politics.
Although Mount Myoboku stood on equal footing with Konoha and normally ignored humans other than their contract holders,
the Great Toad Sage, who could foresee the future, subtly guided the toads' favor toward Konoha.
Naruto had no intention of defecting one day in the future, summoning toads into battle, only for them to return to Mount Myoboku and pass his information on to Jiraiya or Konoha.

That was already the limit of the summoned beasts available to shinobi with deep foundations.
