How dangerous is rat poison outside my fence for my dogs' safety?

Yes, it appears to be safe for dogs and cats. From the website: "It coats the lining of a part of the rodent’s lower gut. This coating of the “fine hairs” in the lower gut, called villi, disrupts the message system to the rodents brain causing it to stop drinking. This leads to dehydration, blood thickening, kidney dysfunction, coma and eventual death." I would still recommend that you place it in areas where your pets do not have access, and certainly not allow them to eat large quantities of this as it could cause vomiting and diarrhea.

There are a couple things you should be concerned about, if your dog is not vaccinated then leptospirosis is a concern as Rats carry it and it is a serious disease in dogs (affecting the kidneys and liver). the main second concern is rat poison, if the rate ingested rat poison in the past couple weeks, then your dog could be poisoned too, these poisons are usually blood thinner which cause an animal to bleed to death, often it has a delayed action and the treatment for that is vitamin K, which must be given by your vet by injection first.

In these cases close monitoring is needed both for any possible wound/injury from the fight and possible poisoning (some of these rats can be poisoned with rodenticide). Any external wound, lethargy, inappetence, signs of cough, vomiting or diarrhoea should be checked by your local vet.

Thanks for using Petco Pet Education Center, formerly Petcoach! While this rat poison has a different mechanism of action that has been advertised as being less harmful to dogs, it has been reported to cause issues in dogs including anemia, gastrointestinal upset, among other symptoms. For that reason, I would recommend that you contact the ASPCA poison control center as they specialize in the more uncommon toxicities in dogs and will have more information on how to proceed from here. Otherwise, have him evaluated by a veterinarian so that they can contact the poison control center for you and proceed with the treatment recommendations. This is time sensitive and he should be evaluated as soon as possible. I am hoping for a full recovery!

It is very unlikely that there would be enough residue to cause toxicity in a dog Ziggy's size as long as you are 100% certain that there was nothing left in the box. With all types of rodenticides you wouldn't necessarily see any signs of toxicity for 12-36 hours, but ingestion of the actual material would be necessary to cause toxicity. If you think there is any possibility that some could be left I would recommend taking a close look at the box and contacting the Pet Poison Helpline: www.petpoisonhelpline.com

The main worrying fact is rat poison, if the rat ingested poison before he was killed by your dog, Gracy could be affected by it (it could be fatal). i would recommend taking her to your vet in order to get vitamin K coverage just in case.

Yes, Diesel is at risk from secondary poisoning from this. You need to take him into a vet immediately to get treated for rat bait poisoning. Do not wait until the morning, and this cannot be treated at home. This is a medical emergency, please take him into a vet now. I hope this helps!
