At the end of the episode, Peaches falls in love with Voodoo the Timberwolf, although earlier, Mr. Turner was trying to find female dogs for Sparky to fall in love with, and Voodoo was the last choice suggesting Voodoo is a girl. However, Voodoo may have actually been a boy and Mr. Turner was just too clueless to check.
Timmy wished that Mr. Turner would like Peaches as much as Sparky did, but Sparky LOVES Peaches, and it's against Da Rules to wish up love.
Mr. Turner and Sparky bring Peaches chocolates, but both of them (especially Sparky) should know that dogs are allergic to chocolate (although Mr. Turner might not know due to his stupidity, or they might not actually be chocolates).
Mr. Turner should have never been in love with Peaches, because according to Da Rules, you can't use magic to make others fall in love.
