1)One of my dogs is a born chowhound; another one has become chowhound too. 2) Have fun pigging out! But do not sleep right after you have pigged out. 3) I love to watch the TV show called Man Vs Food that is about a man literally pigging out all the time.

One of my dogs WAs born to be a chowhound, then another one has become A chowhound,too. 2) Have fun PIGGING OUT! But do not sleep right after you pigged out. 3) I love to watch the TV show called Man Vs Food that is a man literally pigging out all the time 1) Saying 'is born' isn't wrong but 'was born' is better suited here 2) 'Have fun... verb+ing' Think of it like 'to have fun doing something', some examples being 'I had fun swimming in the pool' 'I would've had fun playing at the park had I been allowed to go' 'It was fun getting to know you' 'If you don't have fun at the fair, try and have fun doing something you enjoy' 3) This sentence is fine but it's probably more common to say 'I love watching' than 'I love to watch'... but other than that your use of 'pigging out' here is perfect!! Keep it up!! :D
