If she has SSI - any amount of money she gets will reduce her SSI, as it depends on the state's rules.
If she has SSDI - she can earn up to $1000 or maybe a little bit over before she will have some of her SSDI reduced. She may need to pay taxes, too. She's only at risk of losing her SSDI if she meets SGA (substantial gainful activity), which typically consists of full-time work, but it can also include part-time work, depending on her disabilities.
Ask her if she's willing to work, or if she can work to earn some extra money - at least temporarily.
Ask her if she would prefer donations instead, to keep things simple during her time of bereavement, grieving, and life transitions.
It seems like you're doing a ton of things for her already. Just being there for her is probably a huge help. Donating to her Go Fund Me is also helping, too.
As far as her dogs are concerned, it would depend on the laws there. In certain areas, it's illegal to have more than 4 pets. In other areas, the numbers will vary, depending. She might have difficulty finding a place to accept all of her dogs because of the legalities of that. But maybe she might be able to get some sort of license to keep all the dogs. There might be people willing to foster her dogs for a short time, until she can find a more permanent residence.
The price of purchasing houses are really high - they've inflated everywhere since the advent of the pandemic because the housing market knows that it's safer to live in houses than it is to live in apartments, townhomes, and condos during a pandemic. They capitalized on this so much that most of the houses get bought within days of them going on the market, and many renters were kicked out of their housing rentals. It's unlikely for her to find a house to rent to hold all of her dogs since many of those have been sold or are only being sold (not rented). The best best would be for her to perhaps rent a townhome, duplex, or triplex with a back yard big enough for all her dogs.
But if money is an issue, then she might need to part with most of her dogs, unfortunately. Perhaps she can get visitation rights if the dogs are adopted by nearby families. Meanwhile, she could probably keep 2 of them if she rents an apartment or condo, and perhaps 4 of them if she can rent a townhome, duplex, or triplex. Again, it depends on the laws.
The other option is perhaps renting a trailer home - or whatever they are called.
I wish you the best of luck with your friend. I'm so sorry for her loss!
