Family pet's drug horror

The owners of a beautiful black labrador have made public the horrific event which took place regarding their pet labrador.
During a morning walk in Stricklands Glen with it's owner the dog on their return home the dog took ill. The vet made tests and the results from a forensic labratory confirmed that the dog had ingested cannabis.
The poor animal collapsed and for a short time became blind. Naturally the family were deeply upset.
We have always been a family of black labrador dogs and like any dog they become part of the home. When they take ill it is distressing.
I was horrified to be told of the incident, and find it unbelieveable that anyone would dump, hide or leave drugs in such a public area. I am very upset for the owners but dread to think what would have happened if a small child had found this drug and eaten it. I condem whoever did this - it is disguisting and outrageous.
My sympathy goes to the family and Bella the lovely black lab who is very fortunate to be still alive.
