Polysaccharide　hydrogels　have　emerged　as　pivotal　wound　dressings　due　to　their　inherent　biocompatibility　and　extracellular　matrix-mimicking　properties.　However,　conventional　systems　employing　permanent　covalent　or　physical　crosslinks　suffer　from　irreversibility,　poor　self-repair　capacity,　and　limited　responsiveness　that　compromise　clinical　efficacy.　To　address　these　challenges,　dynamic　covalent　bonding　strategies　have　been　innovatively　integrated　into　polysaccharide　networks,　enabling　unprecedented　functionalities　through　reversible　bond　reconfiguration.　These　advanced　hydrogels　exhibit　intelligent　characteristics　including　self-healing,　injectable　adaptability,　and　stimulus-responsive　drug　release,　achieved　through　precisely　engineered　imine,　borate　ester,　disulfide,　and　other　dynamic　linkages,　which　allows　the　polysaccharide　hydrogels　to　better　adapt　to　different　shapes　of　wounds　and　self-repair　after　damage　to　extend　the　life　of　the　dressing.　In　this　review,　we　summarize　different　types　of　dynamic　covalently　cross-linked　polysaccharide　hydrogels　and　their　applications　as　wound　dressings　in　wound　repair,　discuss　the　prospects　of　polysaccharide　hydrogels　based　on　dynamic　covalent　bonding,　and　address　some　of　the　associated　limitations.　©　2025
