Graze like a goat

It happens that our beloved puppies start eating grass ...
some put themselves on the alarm and the thing is right yes and no.
Sometimes it can be a feeding problem, or the dog has been fasting for too long and needs to expel excess gastric juices ... he often looks for substances that he evidently lacks.
A vet check is always there, but more often than not it is normal for all dogs to do both purebred and not!
it happens that they gorge themselves with grass they vomit and leave more loads than before ... lightened!
