My little Shih Tzu gave birth 7 days ago to 5 pups. All pups are very plump and seem to be doing well. What I am worried about is Gizzy's (mum) a bit low on her calcium levels. I asked the vet to do a blood test as i have read that they can get really ill if their levels go low. Gizzy will not eat any puppy food what so ever (dry or moist) she loves chicken, liver, lambs hearts and turkey and i have started to feed her a complete raw food diet from a company called Natural Instinct that is for working dogs as i also read that this sort of diet is also high and good for whelping mums. She will eat some of this food, some days she will eat a load another just picks at it. I am really worried as i did ask the vet if there was anything else i could perhaps buy to keep her levels of calcium up or could they give me some calcium tablets he said no unless she gets really low they cannot treat her for low levels. I have read on here about the collo-cal-D and have now ordered that, but is there anything else i could perhaps feed her to keep these levels ok. I want to say thank you now for any info. anyone can give me to put my mind at rest.
