Question
I started giving my 9 year old golden retriever cosequin recently for stiffness. She had tibial-plateau-leveling osteotomy (TPLO) surgery when she was 3.
To get her to eat it, I grind up the pills and mix it in with a small amount of yogurt or tuna twice a day.
Would it impact the effectiveness to mix the morning and night batches at the same time and leave one in the fridge all day?
Answer
I would advise against it. I am not familiar with the typical bacteria living and growing in a can of tuna after opening it, but with the yogurt, the bacteria in there will metabolize the glucosamine. This will definitively impact the effectiveness. I strongly suspect this would at least to some extent also happen with the tuna.
Here is one example of Lactobacillus bacteria able to ferment glucosamine. I did not add this before because using glucosamine as a nutrient is not uncommon in general for bacteria (like it is not for humans or dogs).
