Whole new thread I know but I’ve never enjoyed bottle feeding pups and never really gelled with the two I did rear although they went on to make decent workers ,lost two more whilst attempting to feed the litter .I used lactol after a bitch dried up premature ,in fact she was a bad mother spending too much time away from them .Time consuming and don’t think I’d do it again .
On the subject of ivermectin ,these days there no need to use it for whatever reason as there is a spot on for everything now and cheap enough off the web with a prescription from vet .
