Issue with joining tables.

I can't see that you are converting $pet_entry_id into an integer. It will be a string of '0' so the following will not be true.

PHP Code:

  if($pet_entry_id === 0 && $pet_entry_slug === FALSE ){ 


The problem is not the Pet_entry_id.. The problem is when the breed (which is optional) gets a zero value. If the value is different and not 0 them it works fine. I dont want that though, since as i mentioned is optional
