Hi, I can help you with your question today.
Yes, we can definitely see residual activity by the toxin in the poisoned animal.
Did he already eat a poisoned rat?
No, just in case! I have 4 Goldens & a rat problem! I can keep the poison safely away from them but I am worried that the rat will crawl somewhere and die. One of the bitches is young & nosey!
Yes, we term this "relay toxicosis". It isn't commonly seen, but is definitely possible.
There is one type of toxin, called bromethalin, which is less likely to cause relay toxicosis.
However, if the dogs get directly into the poison, this can cause very serious toxicity.
Thanks for that I will have to buy a rat trap I think instead then get someone to kill it for me!
Sounds like the best plan!!!
Good luck getting rid of the critters :)
I do know that the dogs must not get anywhere near the poison!
