Is it safe to give my dog joint supplements, fish oil, and probiotics?

Hi Melanie, I’m am currently giving a joint tablet and fish oil right now. Is this ok instead of the supplement that I just posted? the only difference is that the origin supplement has probiotics, prebiotics and enzymes. What is your opinion? The supplements I am using now are Nordic naturals Fish oil, and cosequin DS joint tablets. Which supplement would you give (the origin or the Nordic naturals fish oil and cosequin DS joint tablet) and why? Thanks!

Hello again! If you are already giving a joint supplement and fish oil, do not give Chloe this additional supplement. Too much fish oil isn't good for her. I'd give the joint tablet and fish oil only. Cosequin is important for her to have for her joint health, and Nordic naturals fish oil is a good brand.

    If Chloe's food does have a ration of 6:1 omega 6's and 3's, then she doesn't need a fish oil supplement. Too much fish oil can have detrimental effects on the health of a dog including interfering with wound healing. The only pill I would recommend giving Chloe would be the joint pill :-)
