Melt white candy melts and coconut oil in a large heatproof bowl. Dip the top of each eclair into the white candy melt mixture and set aside to harden.
Melt the dark chocolate and place into a piping bag. Pipe puppy faces with the dark chocolate.
Roll out a bit of white fondant. Cut out puppy ears, roll out tails and roll out a long rectangle, about 2 inches by 20 inches for the shirts. Place 1/4-inch strips of blue fondant onto the white rectangle of fondant to create stripes. Roll out the rectangle with a fondant roller until fondant is one uniform sheet. Cut into 2 squares and place on the eclairs.
Place the puppy ears and tails on each eclair. Top each puppy head with a red candy melt beret.
