Collo-cal D Over dose

23rd Nov 2014
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 ?

  • Non-Executive Director

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.
