Hi rdpalmer –
I can’t say for sure that the food is the issue, but I can say that Purina Healthy Morsels is an extremely low quality product. Have you read the review? The food contains several “red flag” ingredients and has only received a 1 star rating. There’s nothing “healthy” about those morsels. I would highly recommend you switch to a better quality food. There are several 3 and 4 star foods that won’t break the bank – Pure Balance, NutriSource, Fromm Classics, 4Health, Diamond Naturals, Chicken Soup, Whole Earth Farms, Healthwise, Eagle Pack, Pro Pac, Professional, Premium Edge, etc. Most of these foods are under $45 for the largest bag (~30 – 40 lbs.). The glucosamine is good for the dog with joint issues – you may also want to add chondroitin and MSM in addition to a natural anti-inflammatory like Boswellia or Turmeric. I would not recommend giving your dogs vitamins, balanced commercial foods contain all the vitamins and minerals your dogs need – more is not necessary better as many vitamins and minerals can be toxic when consumed in excess. Changing to a better quality food may help the issues, if not you’ll need to discuss the options with your veterinarian.
