Bringing home a new dog from the shelter is exciting, but it can also bring a mix of concerns—especially if your new companion isn't eating or has an upset stomach. Understanding what's normal and when to seek help ensures a smoother transition for both you and your dog.
✅ Key Takeaways
- ✅ Appetite loss and mild diarrhea are common in newly adopted dogs
- ✅ Set up a vet visit within the first week for a health check
- ✅ Watch for red flag symptoms and seek prompt veterinary advice if needed
Understanding Adjustment Periods 🐾
It's common for recently adopted dogs to experience stress as they transition to a new environment. This adjustment can impact their appetite, behavior, and even digestion. During the first few days, your dog may eat very little, sleep more, and show signs of mild gastrointestinal upset like diarrhea. These reactions are often temporary and related to anxiety or sudden changes in routine.
The 3-3-3 Rule: What to Expect
Many trainers and shelters refer to the '3-3-3 Rule' to describe a rescue dog's transition: 3 days to decompress, 3 weeks to learn your routine, and 3 months to truly feel at home. Patience and consistency are key during this time.
- Keep a quiet environment and provide a safe space.
- Offer familiar or bland foods like boiled chicken and rice if your dog refuses kibble.
- Allow your dog to eat undisturbed by leaving food down and exiting the room.
When to See a Veterinarian ⚠️
While mild stress-related symptoms are normal, some signs require prompt veterinary attention. Establishing care with a vet within the first week is always recommended for any newly adopted dog.
Red Flags That Need Immediate Care
- No eating or drinking for over 24 hours
- Persistent or worsening diarrhea, especially if bloody
- Lethargy beyond normal sleepiness, vomiting, or signs of pain
- Signs of dehydration: dry gums, sunken eyes, or extreme weakness
Some medications provided by shelters, such as dewormers or flea preventatives, can cause mild diarrhea. However, these effects should be short-lived. If symptoms persist or worsen, consult your veterinarian right away.
Supporting Your New Dog at Home
Help your dog settle in by keeping routines calm and predictable. Use gentle encouragement, hand feeding, or quiet companionship. Remember, your new friend is learning to trust you and their new environment.
