Have a Doberman Bitch who has birthed 10 healthy puppies. Obviously, feeding them all has put pressure on the mum. Am giving her the Collo-Cal D as a precaution, so far, absolutely no problems and mum and pups doing well.
Very fast delivery and extremely well packaged.

55 Collo cal d
Verified Purchase

By on 3 May 2016

Small bitch eight in litter. Collo Cal D definitely prevented calcium deficiency (leading to eclampsia). She went to vet to be checked when pups were nearly a fortnight old and had her calcium levels checked. She was perfectly healthy and normal but her levels were slightly down and wouls almost certainly have gone right down without the Collo Cal D. Recommend product highly.

How old do puppies need to be for this


I have 2 week old boxer puppies that I am hand rearing, at what age can they have collo-cal d?

  • VioVet Staff

There is no minimum age for supplementing with Collo-Cal D and this is safe for use in a 2 week puppy as long as you follow the dosing guidelines.

Collo-cal D Over dose

Mr R Fryer

What is the chance of over dosing calcium to a 6 month old puppy fed BAFA raw diet and supplimented with Collo-cal D if given 1ml per 2kg body weight ?

  • VioVet Staff

Collo-Cal D is such a long-established product that a huge amount of experience has been gained regarding its use and potential side effects. The feedback from users gradually gets back to the manufacturer who can then adjust the dose recommendations as required. You can be sure that the recommended dose is a sensible and prudent guideline, and I would recommend that you follow it. Raw meat diets are prone to problems due to lack of available calcium/vitamin D so reducing the dose would carry its own risks. If you go with the recommended dose, you are in good company and I am sure it will give good results.
