Is phosphofructokinase deficiency hereditary?

Certain dog breeds are known to have a hereditary predisposition. If a family history is suspected, speak with your vet about whether genetic or related testing is advisable to assess the risk.

What tests can help diagnose this condition?

Vets typically recommend a complete blood count, biochemistry panel, and urinalysis. Specialized blood tests or advanced imaging may be added if needed, with the next steps planned based on the results.

What tests are needed at follow-up visits?

Routine follow-up typically includes periodic blood draws to monitor blood count and biochemical values. Treatment and revisit intervals are adjusted based on clinical response — always follow your vet's guidance.

What home care can help keep my pet's condition stable?

Record your pet's alertness, appetite, temperature, and elimination daily. Avoid strenuous activity, follow feeding instructions as directed, and attend scheduled rechecks. Contact your vet promptly if anything changes.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

•Noticeably decreased energy and activity lasting more than two days
•Significant loss of appetite or markedly reduced food intake
•Persistent fever or repeatedly abnormal body temperature for more than one day

01What symptoms indicate something is wrong?

This condition most commonly presents as low energy and reduced stamina; symptoms may be intermittent or gradually worsen over time.

Noticeably reduced activity level, frequent drowsiness, or lethargy
Weakness during walking, tires easily, or cannot tolerate prolonged exercise
Intermittent or persistent fever
Decreased interaction, reduced interest in play or external stimulation
Withdrawn or depressed behavior, sluggish responses, or difficulty being roused

Seek emergency care immediately if you notice the following symptoms:

⚠️ Sudden collapse or loss of consciousness
⚠️ Persistent high fever with severely deteriorated mental status
⚠️ Rapid breathing or obvious respiratory distress

02How to assess symptoms at home: monitoring tips and when to seek emergency care

Keeping systematic records at home helps your vet assess how the condition is progressing and whether further tests are needed.

Record your pet's alertness, activity level, and any unusual behavior daily
Measure and log body temperature twice daily (morning and evening)
Track changes in appetite, food intake, and feeding frequency
Monitor and note changes in urination and defecation frequency and appearance
Record short videos of activity and responses for the vet to review
Weigh your pet weekly to track weight trends
If anything seems off, bring your records to the specialist clinic for the vet's reference

03How will the vet diagnose this? Common diagnostic tests

At the clinic, a thorough physical examination forms the foundation, supported by blood and imaging tests to rule out other causes and assess organ function.

Full physical examination

assessing muscle condition, mucous membrane color, and neurological reflexes

Complete blood count (CBC)

evaluating hemoglobin, red and white blood cell counts, and related parameters

Blood biochemistry panel

assessing liver, kidney, and metabolic organ function

Urinalysis

evaluating renal metabolism and detecting urinary abnormalities

Imaging studies (X-ray; CT or MRI if needed) for further differential diagnosis

04How is this treated and managed after diagnosis? Medications, diet, and care guide

Treatment is tailored to each patient's test results and typically includes medication monitoring, nutritional support, and regular follow-up testing.

An individualized treatment and monitoring plan will be developed based on test results
Medication therapy will be monitored by the vet for efficacy and potential side effects
Dietary adjustments to support metabolic needs and maintain stable energy levels
Rest at home and avoid strenuous activity to reduce the risk of episodes
Regular follow-up blood draws and monitoring tests to evaluate disease progression
Discuss long-term care, prognosis, and specialist referral options with your vet

05What to prepare before the vet visit: key information to help your vet diagnose quickly

Note when symptoms started, how they have changed, and any possible triggers

Bring recent temperature logs, feeding and elimination records, or photos

Prepare a medical history summary and a list of current medications and supplements

Use a secure, appropriately sized carrier to minimize movement and vibration during transport

Bring short videos and measurement records to a clinic that can perform blood tests
