Short answer. No, not unless the donation says so. Article 758 presumes that a clause requiring the donee to pay the donor's debts covers only debts previously contracted — those existing when the donation was made — not ones the donor incurs afterward. And even those debts are capped at the value of what was donated, unless the deed clearly states otherwise.
What the law says
When the donation imposes upon the donee the obligation to pay the debts of the donor, if the clause does not contain any declaration to the contrary, the former is understood to be liable to pay only the debts which appear to have been previously contracted. In no case shall the donee be responsible for the debts exceeding the value of the property donated, unless a contrary intention clearly appears.

The default rule looks backward, not forward
Article 758 sets a default reading for a common but ambiguous clause. When a deed of donation obliges the donee to pay the debts of the donor without specifying which ones, the law reads that clause narrowly: it means the debts which appear to have been previously contracted — debts that already existed at the time the donation was made. A donor who takes out a new loan the following year has not automatically shifted that obligation onto the donee, because the clause was never understood to reach forward into debts that did not yet exist when the parties signed.
Why the law reads it narrowly
A donee accepting responsibility for a donor's debts is agreeing to a burden, and the law does not expand that burden beyond what the donee could reasonably have anticipated when accepting the gift. Debts already on the books at the time of the donation are debts the donee could investigate and weigh against the property being received. Debts the donor incurs afterward are not — the donee would be underwriting decisions made after the donation was already complete. That is why the article treats a bare, undifferentiated clause as covering only the earlier debts unless the deed says otherwise.
The value of the gift is also a ceiling
Even for the debts the clause does cover, Article 758 adds a second limit: the donee is in no case responsible for debts exceeding the value of the property donated, again unless a contrary intention clearly appears. A donee who received property worth a modest amount cannot be made to answer, out of their own separate assets, for debts larger than that. Both limits — which debts, and how much — exist to keep a gift from turning into an open-ended liability the donee never truly agreed to.
