info on bottle feeding newborn pup

[High Rock Beagles]

I got two that are 4 weeks old. I've raised many by hand over the past 25 years. Feed every 2 hours the first week. Every 3 hours the second week then when ever they wake up whining there after which is every 4- 6 hours. Very tireing. My wife and I use Hartz powered puppy milk replacer always put kero corn surup or they will get constipated. I've raise more than I've loss,but did loose a lot of sleep. Updated!! Do not use Hartz !!!I have used it for years just lost a litter that was 4 and half weeks old. New container just opened and 8 hours later they were dead. Looked at and smelled it and it wasn't right. I'm mad and my wife is sick!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
