My name is Marianne, and I hope you are able to help me, or lead me in the right direction to get supplies for my pets. First of all, I want to wish you all a merry belated Christmas, and a happy new year

We "adopted" a 4-month-old female pup named Athena, a few days ago. She came with a boat load of fleas. I've given her thorough baths twice now. With dawn, and then with doggy flea and tick shampoo, the fleas are still persistent!!!! We have in total now, 3 dogs, one cat. I've treated the cat with her monthly topical but we need help getting supplies for other cat or finding free stuff. Which was my last treatment that I had. But the other three dogs are still being pestered by fleas, and it has become obnoxious. The pups sadly didn't get their seresto collars from Santa and I'd like to ask if you know where we might get some flea topical or even collars. Our funds are VERY limited until the next paycheck hits, and even then, we might not have enough to get all pups treated. We just got new carpet installed in the house (per the landlords), and between the led that lives outside, and the two inside pups plus cat, I am afraid it'll end up in a flea infestation (I really dislike the combo of deep shaggy carpet and fleas.
Even though I take great care of everything, I am not sure my effort will suffice. Please help me help the pups. The 4-month-old pup we took in, because she was in a horrible homing situation, living with 5 unneutered males that were continuously humping and attacking her, so her former owner wanted her to have a good home away from the chaos. Our indoor cat and 5-year-old Jack chi are both spayed. The LGD is currently pregnant, as she escaped the fence while in heat, and we can't get an appointment for her to be spayed in time and the 4-month-old will be spayed, as soon as we can afford it.
In any way, in the meantime they need to eat. We get the 20 lb. bag of dog food every two weeks, and the cat food once every two weeks as well. But it is simply not enough with the addition of Athena, our newest pup, so we need pet food, supplies and other goods. Please let me know if there is any way you could help us, or let me know where in Tallahassee, FL, we could ask for help with dog and cat food, as well as flea collars or topical flea and tick treatment. My husband is the only income, and it is not enough to get it all done at the moment.
