Hi there, I am so excited because my husband found a guy who have a yorkie for sale in $600, so we went this evening to see the puppy he is 4 months, but he is a cutie, he told us the puppy belongs to his daughter but she start college and he already have 2 dogs so he can afford another one so he needs to sell him so we make a deal with him and we are going to get him tomorrow, we are so lucky, he have his papers and vet record. He is so friendly and playful, the only thing is he needs a proper care, he have a little bit of dandruff but the worst part is that he have a lot lot lot lot of fleas and thicks poor baby he was scratching like crazy and I can notice why right away, so I am going to have a lot of work tomorrow. My question is what kind of shampoo is more effective killing fleas and thicks, but I am saying something GOOD for real because the situation is critic. Any advice will help me a lot thanks
