floor grout

I am not familiar with the contents of floor grout but any substance, foreign object or food not recommended for dogs can be potentially dangerous and or life threatening.  I would suggest a call to your vet and let them know what your dog has been chewing on,  what is in the floor grout if you know and that she is now vomiting.

Most dogs, especially puppies and young adults need to chew as part of their daily activity.  If your dog is chewing while you are not around or is being destructive, she may have separation anxiety.  Providing lots of safe toys to chew and keep her busy will keep her distracted and hopefully away from the floor.  Toys like a Kong that can be filled with treats and peanutbutter, a Galileo Bone or a raw marrow bone from the butcher provide dogs with hours of chew time.

If your dog continues to chew the floor, you may consider a large crate for her to stay in while you are not home to keep her safe.  It is also very helpful to increase the amount of exercise for dogs that chew alot.  A 15 to 20 minute walk in the morning after she has eaten will help release some energy and make sure she has gone to the bathroom before you leave.
