Understanding Common Medical Issues in Rescue Dogs — And How to Help
Rescue dogs often arrive with gaps in care. The good news: most conditions are treatable or manageable with a vet’s plan and a calm, low‑stress home. This guide explains what you might see in the first weeks and how to support recovery with simple comfort tools and good routines.
First Look: What You Might See on Intake
- Parasites: fleas, ticks, intestinal worms, or heartworm.
- Skin/coat problems: mange, allergies, hot spots, hair loss, scabs.
- Ears & dental: ear infections (yeast/bacteria), tartar, sore gums, broken teeth.
- Respiratory: “kennel cough”/upper respiratory infections (URI) — coughing, sneezing, discharge.
- GI upset & weight changes: diarrhea from stress/diet change; underweight or overweight.
- Pain & mobility: arthritis, old injuries, cruciate ligament tears, weak hind end in seniors.

Parasites & Preventives
Expect a fecal check and dewormer from your vet, plus a plan for monthly flea/tick and (where appropriate) heartworm prevention. Heartworm‑positive dogs can be treated under a veterinarian’s protocol; activity is restricted during therapy.
- Flea/tick prevention (ask your vet which product fits)
- Heartworm preventives (Rx via your vet)
- Fine flea comb to monitor progress
- Pet‑safe surface cleaner for resting spots
- Washable bedding — hot wash + dry
Skin & Coat Issues (Mange, Allergies, Hot Spots)
Mange (demodectic or sarcoptic), secondary infections, and allergies are common. Your vet will decide on dips, oral meds, or topical therapy. Keep stress low, prevent scratching/licking, and stick to the full course of treatment.
- Soft recovery collar or recovery suit
- Medicated shampoo (use only if vet recommends)
- Omega‑3 supplement to support skin/coat
- Gentle brush for low‑stress grooming
- Fragrance‑free wipes for between‑baths care
Ears & Dental Care
Head‑shaking, odor, or dark discharge suggest ear infections — your vet will prescribe drops and cleaning. Dental disease is extremely common in adult rescues and may require a cleaning/extractions. Daily care helps prevent recurrence.
- Pain, swelling, bleeding gums, or broken teeth
- Ear hematoma (swollen flap), head tilt, severe odor, loss of balance
GI Upset & Nutrition
Transition food gradually over 5–7 days. Stress diarrhea is common; talk to your vet about probiotics or a short bland‑diet plan. Provide fresh water at all times and measure meals to reach a healthy weight slowly.
- Slow‑feeder bowl to reduce gulping
- Raised bowls for large/senior dogs
- Probiotic supplement (ask your vet)
- Blood in stool, repeated vomiting, lethargy, refusal to eat/drink
- Rapid weight loss or gain, pot‑belly with poor coat (worms)
Respiratory Illness (Kennel Cough/URI)
Mild coughs often resolve with rest and vet‑prescribed meds; separate from resident dogs until cleared. If you see labored breathing, high fever, or blue gums, seek urgent care.
Pain & Mobility
Arthritis and chronic injuries are common in seniors. Vets may recommend anti‑inflammatories, joint supplements, weight management, and gentle activity. Make daily life soft, slip‑free, and easy to navigate.
- Orthopedic bed & warming pad
- Ramps/steps for car and couch
- Support/assist harness
- Joint supplements (ask your vet)
- Never give human pain meds unless a veterinarian prescribes a specific dose
Home Medical Kit for Fosters
- Digital rectal thermometer & water‑based lubricant
- Non‑adhesive vet wrap & gauze
- Pill pockets for meds
- Sterile saline for rinsing minor debris (not for deep wounds)
- Nitrile gloves, scissors, extra towels, spare leash
Preventive Care & Vaccinations
Prevention truly is the best medicine. Core vaccines protect against life‑threatening diseases like parvovirus, distemper and rabies, while optional vaccines (bordetella, leptospirosis, influenza) depend on regional risk and lifestyle. Spaying and neutering not only prevent unwanted litters but reduce certain cancers and behavioural issues. Annual wellness exams, dental cleanings and routine bloodwork allow your vet to catch problems early. For more on oral health, see our Dental Health for Dogs guide.
Recognising Emergencies & When to Seek Immediate Care
Some signs warrant an urgent trip to the vet or emergency hospital: collapse, difficulty breathing, repeated vomiting or diarrhoea, bloated or distended abdomen, seizures, inability to urinate and uncontrolled bleeding. Heatstroke and hypothermia are also medical emergencies—learn the symptoms and first‑aid measures in our Canine First Aid article. When in doubt, call your veterinarian or a 24/7 pet poison helpline for advice.
Working With Your Veterinarian
Establish a relationship with a vet who listens to your concerns and welcomes questions. Ask about diagnostic options, potential side effects of medications and alternative treatments. Seek a second opinion for major diagnoses or surgeries, and don’t hesitate to advocate for pain management and comfort care. Keep copies of medical records and vaccination histories for travel and boarding.
Cost Considerations & Assistance Programs
Veterinary care can be expensive. Compare clinic pricing and inquire about low‑cost vaccine clinics and spay/neuter programs offered by shelters. Review our pet insurance guide for tips on budgeting and reimbursement. For one‑time crises, organisations like the RedRover Relief Fund, Brown Dog Foundation and breed clubs may offer grants.
