After dogs eat hard plastic, they may experience vomiting, poor energy, loss of appetite, constipation, etc. You need to feed the dog some probiotics and then observe whether the dog can vomit or excrete the hard plastic. If there is no discharge for more than two days, it is best to take the dog to the pet hospital for surgical removal.
Tip:
If your dog has blood in his stool after eating hard plastic, then the hard plastic may have scratched his stomach. It is best to send it to a pet hospital for treatment immediately to avoid delaying the condition.
