Scratching and Biting: Intense itching, scratching, licking, or biting at the skin, particularly around the tail base in dogs, and the tail base, thighs, abdomen, head and neck in cats, can indicate a flea infestation.
Hair Loss with Irritated Skin: Patchy hair loss or thinning coat along with inflamed or irritated skin could be due to excessive scratching and grooming caused by fleas or mites.
Visible Parasites: You might see fleas/ flea eggs on their fur, skin, or in their bedding.
Vomiting and Diarrhoea: Parasitic infections, particularly intestinal worms, can lead to digestive issues such as vomiting, diarrhoea (which may contain blood), and mucus in the stool.
Bloating: Pets (particularly puppies and kittens) with intestinal worms often have a distended abdomen or pot-belly.
Visible Worms: Worms may be visible in the faeces or around the anal area.
Weight Loss: Weight loss despite a normal or increased appetite could be a sign of intestinal worms affecting nutrient absorption or energy metabolism. (Note - there are many other diseases that are more likely to cause weight loss with a normal or increased appetite in adult animals!)
Anal Scooting: Pets might drag their rear end along the ground (scooting) due to irritation caused by tapeworm segments around the anal area.
Sudden paralysis and/or difficulty breathing: Paralysis ticks attach to the skin of pets and inject a toxin into their blood stream that can cause paralysis and respiratory distress. Pets who show these signs need emergency treatment from a vet.
