If a dog relapses a month after recovering from distemper, it is likely due to incomplete treatment. Distemper is viral; with active treatment the virus decreases and symptoms ease, but that does not mean full recovery.
If treatment stops then, the virus keeps replicating and reinfection can occur. In addition, a dog’s immunity drops after distemper, and poor nutrition can also lead to relapse.
