Although effective, antibiotic treatment of papillomatous digital dermatitis (PDD) requires extralabel use and there is a (rare) potential for drug residue problems. Practitioners should therefore be aware of nonantibiotic treatment choices. With few exceptions, most of the commercial nonantibiotic formulations marketed for the treatment and/or control of PDD do not have proven efficacy. For this reason, a successful PDD control regimen requires careful consideration of predisposing factors associated with housing, environment, and management. A recently introduced nonantibiotic tripler compound, however, has been found to he effective in short-term trials and may offer a residue-free treatment and control option. Because lesions tend to recur regardless of treatment, periodic retreatment is necessary. In addition, because the precise causative agent(s) and environmental factors that support PDD's propagation are unknown, complete eradication does not seem possible for most herds. However, consistent and timely application of effective treatments combined with appropriate environmental management can provide manageable control. Part I of this two-part presentation reviewed antibiotic methods of treating and controlling PDD, including the use of footbaths, footbathing agents, and topical antibiotic sprays. This article discusses the nonantibiotic options for treating and controlling PDD; establishing efficacy through topical treatment trials; recurrence rates; reasons for treatment failure; disease resistance; potential for residues; and housing, environment, and management considerations.
