That's a great question, and it's smart to think about flea prevention before you have a problem — or to tackle one early if you're already seeing signs.

I'm not able to recommend specific flea medications by name or dosage — that's really a conversation for your vet, who can look at Tigger Webb's full health picture and make the right call. What I can share is some general information to help you feel prepared for that conversation.

What to know about flea prevention options in general:

There are several broad types of flea control products available for dogs:

  • Topical treatments — applied to the skin, usually between the shoulder blades, once a month
  • Oral medications — chewable tablets given monthly or every few months
  • Flea collars — worn around the neck and provide longer-term protection
  • Shampoos and sprays — typically used for active infestations rather than ongoing prevention

Each type works differently, and some are better suited to certain dogs depending on age, weight, health conditions, and lifestyle.

A few things worth mentioning for Shih Tzus specifically:

Shih Tzus have a dense double coat, which can make it harder to spot fleas and can also affect how well topical products absorb into the skin. This is worth mentioning to your vet when you discuss options.

Simple at-home steps while you decide:

  • Use a fine-toothed flea comb through Tigger Webb's coat and check for tiny dark specks (flea "dirt," which is actually flea waste)
  • Wash his bedding regularly in hot water
  • Vacuum frequently, especially in areas where he spends time

When to see your vet: Since choosing the right flea prevention really does depend on your individual dog, I'd recommend bringing this up at your next routine visit — or calling ahead to ask which product they'd suggest for a 5-year-old Shih Tzu. If you're already seeing fleas, excessive scratching, hair loss, or skin irritation, it's worth scheduling sooner rather than later.
