We are hoping our bitch is pregnant, she is on day 22 from first mating. It’s not our first litter (3rd in 7 years)
I’m concerned about too much calcium. I give her natural bio Yogurt but not sure how much calcium is in the Yogurt. I know she’ll be ok to have it at the moment but wondered if it’s ok to carry on

Why bother with yogurt at all, unless she has a tummy upset?   All she needs is her usual good quality diet.   Once you have the litter on the ground and know how many she's going to be catering for, then you adjust her diet.   There's no point before

We’ve always given a spoonful of Yogurt to her, it’s a little treat before she goes to bed and was only wondering if I could carry it on.

Why not just give a few bits of kibble or some other snack??

I would prefer to keep giving the Yogurt, if it’s safe to do so, I only want to know if it contains too much Calcium for a pregnant bitch. It’s not a problem if I have to stop giving it but she really does enjoy it at bedtime
