How to comfort a dog with congestive heart failure is a question many pet owners face as their elderly dogs experience this heart condition. Congestive heart failure (CHF) is a serious heart disease often seen in older dogs. But, with good care, caregivers can make a large improvement in their quality of life.

This article offers a guide on eight important aspects of home care:

  • Medication

  • Sedatives

  • Quiet environment

  • Stress reduction

  • Regular check-ups

  • Dietary management

  • Appropriate exercise

  • Emotional support

Dog owners can help their pets live longer and feel better by following these principles.

1. Medication Management: Accurate Use and Side Effect Control

1. Diuretics: The Core of CHF Treatment Furosemide (2-4 mg/kg bid) is the cornerstone of CHF treatment. It reduces fluid retention by inhibiting kidney tubule reabsorption. Monitoring: Weigh your dog weekly. If their 24-hour urine output is over 100 ml/kg, this shows a risk of overdose. Doctors can use potassium-sparing spironolactone to prevent hypokalemia. Emergency Response: If the dog has trouble breathing, give 1/4 of the normal dose. You can do this up to two times in 24 hours.

2. Sedative Use: Caution is Key Indications: Use sedatives like acepromazine (0.05 mg/kg IM) only for severe anxiety or emergencies. They may cause hypotension, which might require vasopressors.

Alternative: Prefer natural sedatives like L-theanine (100-200 mg/d), which reduces side effects by 70%.

2. Environment Optimization: Designing a Living Space That Promotes Heart Health

1. Noise, light, temperature, and humidity controls.

  • Noise: Keep noise levels below 45 dB. This helps to prevent loud, sudden sounds.

White noise machines can help mask unexpected noises. Temperature & Humidity: Maintain room temperature between 18-22°C and humidity between 40-60%. Change water daily in humidifiers to prevent bacterial growth. Light: Mimic natural day-night cycles. Use a 3000K warm light night lamp during the night to avoid bright light stimulation.

2. Rest Area Configuration       Sleep System: Choose an orthopedic memory foam dog bed with a 15° tilt to relieve heart strain. The mattress should be at least 10 cm thick. **Supportive Equipment:** For severe respiratory distress, make a wedge-shaped cushion at a 30° incline. Use an oxygen tank set to 2 L/min.

3. Behavioral Management: Creating a Low-Stress Lifestyle

1. Daily Activity Plan

Energy Management: Use the "5-minute rule." Limit each activity to 5 minutes. Total daily activity should be no more than 20 minutes.

Elimination Plan: Choose flat, short routes for walks, and use a pet stroller for distances over 100 meters.

2. Social Limitations Visitor Management:

  • Install a video doorbell to alert you to visitors.

  • Keep the dog in a separate room.

  • Use a pheromone diffuser to calm anxiety.

**Interaction with Other Pets:** Avoid direct contact with other animals. You can let them see each other through a glass window for up to 10 minutes.

4. Medical Monitoring: Establishing a Warning and Response Mechanism

1. Home Monitoring System       Respiratory Rate: Check three times a day (morning, afternoon, and before sleep). If the rate exceeds 35 breaths per minute, it may indicate a potential crisis.       Mucous Membrane Color: Use a mobile app to track changes in gum color. If it turns gray or bluish, seek medical attention immediately.

2. Medical Testing Schedule

  • Lab Tests: Do tests every three months for:

    • Kidney function (BUN, creatinine)

    • Electrolytes (K⁺, Na⁺)

    • NT-proBNP (heart failure marker)

**Imaging Re-examination:** Do a heart ultrasound every six months. Focus on the left ventricular end-diastolic diameter (LVIDd).

5. Nutritional Intervention: Heart-Specific Diet Plan

1. Dietary Adjustments       Calorie Control: Maintain ideal weight. For obese dogs, reduce daily calorie intake by 20%, and use heart-specific prescription food (like Hill's h/d).       Key Nutrients: Supplement with L-carnitine (50-100 mg/kg/day) and taurine (100 mg/kg/day), and limit sodium intake to <0.2% of "dry" matter.

2. Feeding Optimization

  • Meal Distribution: Give 3-4 small meals each day. Use a slow feeder bowl to help control eating speed and prevent choking.

Hydration: Offer ice cubes as a substitute for drinking large amounts of water. You need to control total daily water intake at 40-60 ml/kg.

6. Exercise Rehabilitation: Designing Safe Activity Levels

1. Exercise Prescription       Intensity Level: Use the modified Borg scale of perceived exertion. Ensure that the breathing rate does not increase by more than 20% after exercise. **Activity Selection:** Therapists prefer water-based rehab at 32°C. Buoyancy eases the strain on the heart. Perform two sessions per week, each lasting 10 minutes.

2. Emergency Stop Criteria: Stop activity right away if any of these happen:

  • Respiratory rate goes over 40 breaths per minute.

Mucous membranes turn gray or white. The dog experiences instability or has frequent coughing episodes.


7. Emotional Support: Deepening Emotional Connection

1. Owner's Behavioral Adjustments

  • Body Language: Keep eye contact by squatting. Make slow movements and use a gentle tone when speaking.

Interaction Methods:  

  • Offer three sessions of five-minute gentle massages each day.

  • Focus on acupressure points, such as Baihui and the Pericardium meridian.

2. Environmental Enrichment Plan

  • Olfactory Stimulation: Use heart-safe sniff pads. Hide low-sodium treats inside. Keep each session to 10 minutes or less.

Music Therapy: Play classical music designed for sick pets (60-80 BPM) for 30 minutes twice a day.
