Immediate action is essential. Here's what you can do: Contact the Veterinarian: If the rescue/shelter has a designated vet, contact them immediately. If not, take the dog to your nearest veterinarian. Inform the Rescue/Shelter: Keep the organization in the loop regarding any health issues or concerns. They might provide guidance or additional resources. Monitor Closely: Be vigilant about noting any changes in behavior, appetite, or physical condition, and communicate these to the veterinarian.
