A palindrome for "male" could be "elam," and a palindrome for "female" could be "emalf." Both are safe for kids to see and understand.
The palindrome for a female dog is called a "bitch." In this context, a palindrome refers to a word that reads the same forwards and backwards, but "bitch" itself is not a palindrome. A true palindrome related to dogs would be a playful term like "dog" which reads the same way in reverse, but it doesn't specifically refer to a female dog.
