so i had shared the story before of my one year old boxer who had eaten the padding underneath the carpet he was sick for about a week but eventually got over it - he has been doing okay since then but this last week has seemed to be sensative to his stomach - vomiting the next day after he eats- (i have kept him on a light diet )his vomit is yellowish/brown and smells very badly - what can this be? he is new to me so his behavior is still unknown. we have had him about 2 months or so my other boxer is healthy and happy????
