Common vitamins and supplements for dogs include multivitamins, omega-3 fatty acids, glucosamine, and probiotics. However, it's important to consult with a veterinarian before giving any supplements to your dog to ensure they are appropriate and safe for your pet's specific needs.
Hi! Have you looked at Purina's range of supplements? They have 5 different ones that focus on different things (mobility, skin and coat, natural defences, relaxation, and multivitamins). I tried the mobility one for my senior dog last year and I'm never going back. It helps support his joint health so he's been a lot more active during walks. I have a friend who tried the relaxation one for her anxious dog and it's done wonders for him too. He's a lot more chilled out and less reactive when people walk past the house. Other than that, I don't really give my dog supplements. Apart from chew sticks for his dental health :) Hope this helps!
