The most obvious sign that your Maltipoo puppy has fleas is that he's scratching. But because that's also common dog behavior, here are some other warning signs that your pooch might be in need of special flea treatment:
-His fur may be missing or falling out in spots – this might be due to excess scratching, fussing, or even just a physical reaction to flea bites.
-Presence of flea dirt in his coat – these rusty-colored small specks are one sign that fleas are active in your puppy's fur, and you may also find them on the furniture where he sits.
-Red rashes or spots on your Maltipoo's skin can also indicate he is reacting to flea saliva.
-If you notice any of these symptoms, it's a good idea to take your puppy to the vet.
