Q. Isvegetable oil toxic for dogs
A. No, but I suppose it depends on how you mean. Did your dog drink an entire bottle of vegetable oil? If so, you should probably see a vet. Did you add some to their food? That's okay, just don't make it a regular thing, as it's truly an unnecessary ingredient. Did you accidentally spill some, and your dog licked some up? That's okay too.
If you're interested in teaching your dog a "leave it" command for accidents like vegetable oil spills, purchase a consultation with me and I can go over any behaviors you're interested in teaching your pup!
