Symptoms of fleas
Itchiness and skin problems: persistent itching, skin infections and hair loss. Some dogs develop flea allergy dermatitis, which is the most common skin disease in dogs.
• Anaemia: fleas suck blood, leading to anaemia, especially in young or old dogs. Severe cases can be lethal. •
Parasite transmission: fleas can carry tapeworms that infect dogs, causing anal itching and nutrient loss.
When to contact your vet
If you notice any fleas on your pet or any of the above symptoms, contact your local practice.
Diagnosis of fleas
Diagnosis involves identifying adult fleas or fleas' dirt on the pet’s coat, or signs of flea allergy such as redness, bold patches and itchiness around the back of the pet and the base of their tail and the back of thighs.
Treatment and prevention of fleas
Use of medical products prescribed by a vet will kill fleas on the cat, as well as use of products to spray the home.
Washing all bedding material in hot water and vacuuming the house.
Preventing fleas is simple with year-round use of vet-prescribed products. Understanding the flea life cycle and committing to a prolonged treatment plan is crucial for effectively managing and preventing infestations.
Outlook
Flea infestations can be treated, but it may take some time to fully resolve. Once the fleas are gone, it’s essential to use preventative measures to keep them from coming back.
