i be an avid dog lover which be one reason i have to see this movie . watch character and personality evolve out of dog breed and status be a very funny comedy bit while a mexican dog will speak with a spanish accent and so on . the relationship of dog and cat to humanity in this movie be quite strain while i think disney homeward bound and the doctor dolittle movie with eddie murphy hit it a lot closer . another thing quite strain be the concept that dog and cat could create such an elaborate hidden society with their own rule and technology level be quite ridiculous . once you get past the inane concept and you have a very funny and live action cartoon for the whole family include the family pet . i be sure youre never look at your cat or dog the same way again .
