TL;DR: If your dog eats several paintballs, contact your veterinarian immediately as the ingredients can cause life-threatening dehydration and sodium poisoning.
What happens if my dog eats paintballs?
Paintballs are typically composed of a gelatin shell filled with a mixture of polyethylene glycol (PEG), mineral oils, and dyes. While these ingredients are usually non-toxic to humans, they are osmotically active. This means they can pull large amounts of water into your dog's intestinal tract, which can lead to severe dehydration or potentially life-threatening electrolyte imbalances, specifically sodium poisoning.
Is it an emergency if my dog eats paintballs?
- The urgency level for this situation is Medium.
- While eating one or two paintballs may only cause a mild upset stomach in a large dog, eating several—especially for small or medium-sized breeds—poses a significant risk.
- Contact your veterinarian or a pet poison control hotline immediately.
- Do not wait for symptoms like tremors or seizures to appear, as these indicate advanced salt poisoning.
How does taking a photo of the paintballs help my veterinarian?
- Take a clear photo of the packaging or any remaining paintballs to show your veterinarian.
- Because different brands contain varying concentrations of chemicals and dyes, a photo allows the vet to quickly identify the specific product.
- Visuals help the vet estimate the total volume of ingredients ingested.
- This information helps determine the best course of action, such as whether to induce vomiting or start IV fluid therapy.
Clinical Context (Merck Veterinary Manual)
Following ingestion of paintballs by a dog, urgent triage should include assessment for potential clinical signs such as vomiting, with or without blood, which may be followed by hypovolemic shock, depression, fever, acidosis, and potential liver failure 12-24 hours later. Oliguria and anuria secondary to shock-induced renal failure may also occur. Radiographs may reveal obvious foreign material or delayed gastric emptying. In cases of GI obstruction or perforation, endoscopic or surgical retrieval is recommended.
