'I'm a vet and this is why your dog eats grass and what it might say about their health'

The age old question 'why do our pets like to eat grass?' has left many a dog owner baffled down through the years.

However one veterinarian has decided to ally those fears by identifying a number of key warning signs that demonstrate your dog's deteriorating health, RSVP Live reported.

Vet Dr Marty Goldstein, believes there may be an important lesson behind the question, as he emphasises that some owners may be overlooking vital symptoms from their pets, telling you that they are not well.
