> She is 5 weeks at the moment and has turned back into a puppy. She is charging around the garden at times and then absolutely zonked the next. I'm really not sure how I will be able to slow her down as she gets bigger. Really hoping that her size will slow her down
Being pregnant isn't being ill and provided she doesn't really exhaust herself, or get knocked, charging around will keep her lean and fit - all good for the whelping. As for 'puppy food' - I really don't know when this started!! Puppy food is for PUPPIES. Provided she is getting a good quality food, and should have been before she was bred even, there's no need to be piling food into her. Not until you SEE what size her litter is. You want her lean, not carrying fat through her pregnancy. Her puppies will take all they need both before and after whelping and it's the after whelping, going into the second week and up to weaning, that you need to make sure she's getting enough. And again, her normal diet, plus a bit of extra protein, if needed.
You will, if she's carrying a big litter, have to split her daily intake into several smaller meals, as the litter will be taking up a lot of room inside.
If she doesn't have enough teats, you'll have to regulate the feeding - putting any smaller puppies on first so they get their share before the bigger pups push them off. And you may be looking at supplementing, half on, half off. But WAIT. Scans aren't accurate and only show how many at the time of the scan. Anything could happen between now and whelping.
" I will get some calcium tablets, and I already have nutri drops. " By all means lay in what you think you might need, but be warned, do NOT give any extras until you see if this is needed, and on the advice of your vet.
