You do everything you can to keep your new puppy happy, and having fleas is definitely not a happy time. Keep these tips in mind to keep your puppy healthy, happy, and flea-free.
The common flea not only causes your dog discomfort, but it can also transmit disease, pass on tapeworms, and cause anemia, especially in vulnerable puppies and older dogs. Regularly inspect your dog for any signs of fleas. Intermittent scratching, biting, and gnawing, plus evidence of flea dirt between your dog's back legs or on top of his rump, are telltale signs of fleas. If your dog is constantly biting and gnawing himself or you can actually see fleas, you've got a full-blown infestation. To check out your dog for fleas, have him stand in a bathtub and vigorously rub your hands through his fur. If little dark dots fall on the tub floor, they're likely either fleas or flea 'dirt' (excrement). You'll know you've got fleas if the 'dirt' turns red when you add a drop of water.
These products work by preventing fleas from biting or reproducing. They are the flea control methods of choice, and when used faithfully as directed, help pet owners avoid many dog health issues associated with fleas.
Does your mature dog sniff at his bowl and walk away instead of digging in? You may think he’s just being picky, but it’s important to keep an eye on how much he’s eating — especially if he’s a senior. While age-related diminishment of the senses of smell and taste may account for some of his disinterest in food, appetite loss can also indicate a serious medical problem.
“It’s important to give your dog enough calories because weight loss can be debilitating to senior pets,” says Wendy Brooks, D.V.M., who warns that a loss in appetite should be mentioned to your vet. A good rule of thumb: If your pet hasn’t eaten in a day, make a visit to the vet. Here are six ways to entice your canine friend with a nourishing meal.

Many animals find canned food more palatable because they like the taste and texture, Brooks says. You can top their favorite dry food with room-temperature wet food.
Dogs like a warm or room-temperature (not hot or cold) meal. Avoid serving him day-old wet food from the refrigerator, and keep his food away from heat. Another reason he might not be eating: It's too hot outside.
Dogs prefer consistency when it comes to their food. Don't change every day, but try a new flavor, such as lamb or chicken, and see if he responds (it may trigger his sense of smell). To avoid an upset stomach, introduce a new food by mixing it with his old food in equal increments each day.
Common mature-dog health issues, such as arthritis or joint pain, can make it difficult for him to access his bowls. Keep food and water where he spends most of his time. Put a water bowl on all floors of the house, too.
Older pets are at a higher risk of dehydration. Provide a clean bowl with fresh water at all times. It will help prevent disease, such as a kidney condition, and aid in digestion.
Dogs are people pleasers. If you see him eating, give him a little verbal reward. He'll know it makes you happy and will repeat the behavior.
