My senior dog has skin bumps and matted hair. Should I see a vet?

Updated On September 23rd, 2025

Pet's info: Dog | Bichon Frise | Male | neutered | 12 lbs

My 11 yr old Bouchion has been on a vitamin supplement Dinvite for one year . I ran out last month. His hair was really overgrown and matted for 3 months . He all of a sudden broke out with coarse bumps some pustules were draining . I changed his diet to Castermix organic Salmon. Got his hair cut low to skin. The groomer used a medicated shampoo. What I can't decide is should I take him to the vet to rule out a bacteria infection or put him back in Dinovit and see if he get better.

Yes, at this point, Cosmo should take a trip to the vet. From the pictures, his skin lesions are highly suspicious for a bacterial skin infection. This may have occurred as a result of matted hair or underlying allergies. If he did well on Dinovet in the past, it may be worth restarting this supplement (double check with your vet first!), but I doubt that this alone will be sufficient to manage these lesions. I hope that he's on the mend soon!
